How to make a permanent magnet with your own hands. How to make a neodymium magnet at home. Production of neodymium magnet

In this article I want to tell you how you can make a pretty magnet with a photo of a refrigerator. And not only to make, but also profitably sell.

My site is initially dedicated to sublimation printing. But this does not mean at all that it is possible to earn only selling mugs, plates, puzzles and other sublimation products. Ideas are a lot! It is the thermal transfer and the manufacture of clocks with a photo portrait and printing a variety of calendars and a lot of things.

The first article about magnets.

Most of all, simplicity is attracted to the manufacture of magnets from Vinyl (no equipment) and a chic chest in price. Judge for yourself - a magnet of 65 x 90 mm in size is less than 5 rubles. I sell it in gardens for 120 rubles!

Magnets are different - plastic, metal, sunset. We will make a magnet based magnetic vinyl. He looks like this:

In a nutshell, this is the most common photo pasted on magnetic vinyl.

Choose any photo frame and insert a photo of a child. Photo frame can draw yourself or download on the Internet. Do not forget about copyright rights. Not all authors allow making money on their framework and templates.

For the manufacture of a magnet, we will need the simplest tools:

This is a small cut glass, a stationery knife and a metal line. And it's all? - you ask! Yes, this is enough to earn good. You do not even have to have your own printer. You can always order a photo printing on the side. And your magnets from this will be more expensive not much. Later we all consider.

A few words about magnetic vinyl. It is sold in rolls, usually 30 meters. Such a roll is not only quite expensive, but also very heavy. And this increases the shipping cost for those who ordered vinyl by mail or through a transport company. Those who have a nearby company Zenon was lucky more - there they will sell at least a polymer of magnetic vinyl. Agree, it is very convenient.

Magnetic vinyl is produced different thickness. I recommend to manufacture magnets to acquire vinyl no thinner 0.7 mm. Magnets from a thinner vinyl look cheap and not solid.

Also, the magnetic vinyl happens to the adhesive layer and without the adhesive layer. With adhesive layer has a protective film and with an equal thickness costs a little more expensive.

You can choose a bundle:

Magnetic vinyl with adhesive layer + ordinary photo on paper

Magnetic vinyl without adhesive layer + photo on a self-adhesive photo paper.

I will use the second option. I have a vinyl without glue with a thickness of 0.75 mm and for the inkjet printing of Privision.

So, proceed to the manufacture of our magnets.

I think, find a cute photo frame for you will not be a lot of work. We assume that you already have it. Pick the photo frame under the size you need - I have 65 x 90 mm. With this size on the A4 sheet, 9 magnets are placed. Of course, you can choose absolutely any size.

You also photographed children. It remains to insert photos into the frame. It can easily be done with or.

By the way, how to photograph children in kindergartens and schools and process photos will soon appear on the site a large section. Do not forget not to miss the announcement.

Photos are inserted, now they must be placed on the sheet and print. You can use photoshop for this, I like CorelDRAW. I import on one photo frame and placing on a sheet A4. If you order more than one magnet, duplicate the required number of times.

All photo frames are placed, self-adhesive photographic paper is inserted into the printer. We send a sheet to print! We print conventional water ink.

Now we will stick a photo paper on magnetic vinyl. I first cut it on the sheets of A4 format. More precisely, they turn out a little less than - 20.5 x 29 cm. The width of the magnetic vinyl roll - 61.5 cm. Drawing equally for three parts. And the length is specially slightly reduced, with my sizes of magnets it is quite enough. You also try to calculate everything so that the waste is smaller.

So that the photo paper lay down on vinyl smoothly without bubbles and folds, just see how I do it and repeat.

First, turn down the sheet down face and on the short edge of the self-keeper, remove the protective paper by about 15 mm.

Now we turn the sheet and holding the edge with a bent paper (not letting it stick), we have a sheet exactly on magnetic vinyl.

By placing a sheet as you need, carefully glue the edge of the sheet to vinyl and well join with a dry soft cloth.

Now our sheet is reliably fixed on magnetic vinyl and will not move anywhere. We put the left hand under the sheet, capture the edge of the protective paper and begin to dramatically pull to the side, exposing the adhesive layer, and with the right hand using a rag with progress movements up-down smooth leaf to vinyl.

So smooth to the end.

Set aside the resulting sandwich on the side of 15 to 20 minutes, so that the adhesive layer fell pregnant. Now the magnets can be chopped. Ideally, a saber cutter is suitable for this purpose, but without it you can do perfectly.

Metal ruler and stationery knife is what you need. To cut the knife, and did not tear the paper on the vinyl, hold the angle of the knife as small as possible to the surface.

Update the blade of the knife, labeling the smoking part. Usually I do this after cutting the next sheet of A4 format.

Here are the first nine magnets are ready.

Each magnet I put in a separate bag. I have 75 x 120 mm. This bag is worth a penny, and the parents are individual packaging very much.

That's the whole process. As you can see, nothing complicated. And now let's count a little.

Magnetic vinyl without glue with a thickness of 0.75 mm I bought 310 rubles for a pattern of a meter (width 0.61 cm), which is 504 rubles per square meter or 30.3 rubles per sheet A4 (rounded up to 31 rubles).

I bought a 100 rubles for 20 sheets of A4 format. So one sheet costs 5 rubles.

31 + 5 \u003d 36 rubles.

36 rubles: 9 magnets \u003d 4 rubles per piece!

Let me remind you that I sell them for 120 rubles. I know that some sell such magnets for 150 rubles.

Now a couple of words about quality. Aquatic ink has a serious drawback - they will quickly burn out. Especially compatible ink. If the refrigerator of your customers is at the window, then the magnet on his door can fade in the year. In this case, I will advise you to print photos in the photo laboratory and glue them to vinyl with adhesive layer. With such a situation, the cost of your magnet will grow by 2 - 3 rubles, but it will not hang out for many years.

Alternatively, the magnet can be covered with thin cold laminate (laminating film). It complicates a little much, but the magnet looks just great!

You can also purchase an inexpensive corner trimmer and beautifully cut the corners of your magnets.

In short, I gave you an idea. How do you implement it in practice entirely depends on you. Now and you know how to make a magnet with a photo. Believe the word, such magnets use in kindergartens and schools in constant demand!

Neodymium magnets in our time densedly replaced simple. They are made of ndfeb metals alloy, characterized by large magnetic properties. Result: The device is better than magnetite and much more resistant to demagnetization, unlike the usual one.

What can be made from a neodymium magnet, consider in the material.

The first thing comes to mind is the production of toys and puzzles from this alloy. As a rule, for these purposes it is not the strongest magnet, which is made in the form of balls. Crafts from a magnet can be drawn up in various figures and from neodymium can be formed complex sculptural forms in miniature. But it is important to remember that such a toy is forbidden to give children up to 6 years.

A pair of magnets, which turned out in the stomach or intestines, can hook the esophagus walls, which in turn will entail perforation, and the victim will inevitably be in the hospital.

You can make different locks from the magnet from the magnet. A pair of medium magnitia magnets can be used as a vice. The use of alloy, in this case, is much more practical, in contrast to the vice metal. Details of non-standard forms will be fixed more reliable.

For car enthusiasts, this alloy is generally indispensable and can be used very diverse. For example, not everyone knew that the magnet can be used to filter oil in the oil filter. If you install it on a drain plug in a movable crankcase, then the entire metal garbage will accumulate at the installation site, which will subsequently facilitate its removal.

With the help of magnets it is convenient to search for small metal objects: for example, needles or pins on the carpet darkest. Neodymium can be used to search for metals in Earth or various communications in the walls.

The device is suitable for magnetizing various items made of steel, such as screwdrivers, needles and not only. With it, a tool or other steel inventory is recorded. Properly installed magnetic holders will help correctly distribute the tool in the workshop or even in the kitchen. In addition, the alloy of such power can be magnified even the old demagnetic magnet.


It is often used to format information on electronic media. Information with video and audio cassettes, as well as from a hard disk and from credit cards with a powerful magnetic field is permanently removed.

Options for using magnets in everyday life

Neodymium magnet is widely used in everyday life. The main thing is to be able to show fantasy. There are standard methods, and very interesting use methods.

Amazing shelf for spices

To spices are always at hand and did not occupy a lot of space, you can construct a special shelf using neodyms. To do this, you will need:

1. Metal jars with a transparent lid.
2. Magnet from neodymium with a diameter of 1.5x6 mm.
3. Epoxy resin.
4. 100th grain odds.

We process the bottom of the jackets outside and with the help of a resin we stick magnets. After that, they will be reliably held on any metal surface.

Lifehak: Metal surface can be created independently. Just attach to the usual coating metal plate. If it is missing, use what is. For example, the door of the refrigerator. At the same time we recommend familiar with the master class to create without dust and worries.

It turns out beautiful and gently.

Scissors and household tools at hand

Knives, scissors and other household utensils can also be attached to neodymium locks. To do this, it is enough to choose a suitable place, create a strip from a magnet and set. And then the kitchen utensils will always be at hand.

By the way, for this you can use magnets from speakers, most importantly, it is beautifully issued.

Method of storage of beer

So that the beer package does not occupy an excess space in your refrigerator, you can simply hang the bottles to the ceiling of the refrigerator. Just getting a tape with magnets https://mirmagnitov.ru/catalog/gibkie-magnity/magnitnaya-lenta/ and attach it.

The magnet power will be enough to keep the bottles reliably.

Orangery using magnets

To surround yourself with home plants, it is not necessary to acquire large pots and put them on the shelves. It is enough to create small containers, for example, from traffic jams and plant favorite plants.

After that, to locate around yourself in such a way as you like more.

Opener for bachelor

Such adaptations will appreciate any man who does not have a woman in the house. A decorative plate with a beer opener is installed on the wall, on which the magnet is fixed on the reverse side.

Now you do not have to collect traffic jams all over the apartment - they will remain on the opening. By the way, this will create some collection of drunk.

Decision on wearing tools for masters

So that the tools and fittings are always at hand you can make magnetic bracelets and belts in which the alloy will be inside. This will allow the belt on the belt is not a very heavy tool, but on the bracelets to sculpt fittings.

And since the magnet has healing properties, then you get an additional bonus.

Space for triggers

Any beauty has a huge number of studs, but, as a rule, they are often lost. Therefore, you can attach a magnetic tape inside the wardrobe or on the wall of the cosmetic bag, and then all the hairpins will always be in one place.

Shelf for cosmetics and women's accessories

This device is also created on the principle of the shelf for spices.

A steel surface and magnets, glued to the bottom of cosmetic cases, will be required. A similar surface is installed next to which hooks are attached with the help of neodymium. They can hang their decorations.

Housekeeper

Next to the exit (in the hallway), the magnetic panel and key rings are installed on the wall. Keys will never be lost again.

Also, these panels can be attached lighters and other little things that may be required to you outside.

Nothing to forget

With the help of magnetic holders, you can leave notes or write a list of cases for tomorrow, after which it is fixed on the most prominent place. This will allow not to forget the little things and always remember what needs to be done.

Order in childhood

Toys with magnets installed in them are easier to store on metal surfaces. Thus, the child will become more interesting to carry out cleaning in the room, which will help to achieve a long-awaited order in the nursery.

Study without leaving home

Every child needs to learn, but the time has passed when the children wrote on the desks. Now you can make a marker board for a child, on which there will be a magnetic panel. You can attach all the necessary tools to study.

Lego do it yourself

You can make or order small details of various shapes and sizes, glue them magnets and on a large metal surface to create a wide variety of designs.

These figures can be constructed with each other, which will allow a small creator to develop in a creative key.

Healthy sleep on a magnetic pillow

Orthopedic magnetic pillow will allow fully rest during sleep. But before it uses it is necessary to consult with the doctor, since there is a contraindication. For example, the presence of a pacemaker in a patient.


Magnet can be used for various things, the area of \u200b\u200bits use is almost immense and the properties of this alloy are of great importance when used. In the skillful hands, you can make a huge number of desired and useful things and accessories.

Magnets greatly facilitate life. Look in the video as immediately apply the knowledge gained in practice!

The electromagnet is a magnet that works (creates a magnetic field) only when flowing through the electric current coil. To make a powerful electromagnet, you need to take the magnetic core and wind through its copper wire and simply skip the current on this wire. The magnetic pipe will be magnified by the coil and starts to attract the iron items. Want a powerful magnet - raise the voltage and current, experiment. And in order not to suffer and not to collect a magnet itself, you can just get the coil from the magnetic starter (they are different, on 220V / 380V). Take this coil and insert a piece of any piece of iron insert (for example, a conventional thick nail) and turn on the network. This will be a truly bad magnet. And if you do not have the opportunity to get the coil from the magnetic starter, now we will look at how to make an electromagnet itself.

To assemble the electromagnet, you will need a wire, a source of direct current and core. Now we take our core and wind the copper wire on it (Better coil is better, and not in the ball - the efficiency will increase). If we want to make a powerful electro magnet, then we wash in several layers, i.e. When the first layer was wound, go to the second layer, and then we wash the third layer. When winding, consider that what you wrap is, this coil has reactive resistance, and when flowing through this coil will pass a smaller current with a large reactive resistance. But also consider, we need a current, because we will magnify the core, which serves as an electric magnet. But high current will heat the coil, according to which the current flows, so relate these three concepts: the resistance of the coil, current and temperature.

When winding the wire, select the optimal thickness of the copper wire (somewhere 0.5 mm). And you can experiment, considering that the smaller the cross section of the wire, the greater the reactive resistance and, accordingly, the current will leak. But if you wake the thick wire (approximately 1mm), it would not be bad, because The thickness of the conductor, the stronger the magnetic field around the conductor and plus the larger current will proceed, because Reactive resistance will be less. The current will depend on the voltage frequency (if from AC). It is also worth saying a few words about the layers: the more layers, the greater the magnetic field of the coil and the stronger the core will be magnetized, because When layering layers, magnetic fields are folded.

Well, the coil wrapped up, and the core insert inserted, now you can begin to feed the voltage to the coil. Let's supply voltage and start to increase it (if you have a power supply unit with voltage adjustment, then smoothly lift the voltage). Be watch our coil getting warmed. We select the voltage so that when working the coil was slightly warm or simply warm - it will be the nominal mode of operation, as well as it will also be possible to learn the rated current and voltage, measuring on the coil and find out the power consumption of the electromagnet, moving the current and voltage.

If you are going to turn on the power outlet 220 volts electromagnet, then you must measure the coil resistance at first. When flowing through the current coil in 1 amp, the coil resistance must be 220 ohms. If 2 amps, then 110 ohms. Here's what we consider the current \u003d voltage / resistance \u003d 220/110 \u003d 2 A.

All, turned on the device. Try to bring the carnations or paper clips - it must take. If it takes poorly or very badly, then the domidate layers are five copper wire: the magnetic field will increase and resistance will increase, and if the resistance increases, then the nominal data of the electro magnet changes and will need to reconfigure it.

If you want to increase the power of the magnet, then take the horseshoe core and wrap the wire to two sides, so it turns out the horseshoe manite consisting of a core and 2 coils. The magnetic fields of two coils will be formed, which means that the magnet will operate in 2 times more powerful. The diameter and composition of the core plays a big role. With a small section, it turns out a weak electromagnet, even if we deliver high voltage, but if you increase the segment of the heart, then we do not have a bad electromagnet. Yes, if another core is an iron and cobalt alloy (this alloy is characterized by good magnetic conductivity), the conductivity will increase and due to this core will be better magnified by the coil field.

Conclusions:

1. If we want to collect a powerful electromagnet, then we wash the maximum number of layers (the wire diameter is not so important).
2. The core is best taken hiking (you just need to power the 2nd coils).
3. The core should be made of iron alloy and cobalt.
4. The current, if possible, should proceed as much as possible, because it is he who creates a magnetic field.

Sometimes ask how to make a neodymium magnet with their own hands. Let us try to figure out how much it is possible, and that in general is the process of producing such products.

Thus, the devices sold by us consist of an alloy, which consists of 70% from iron and almost 30% from boron. Only some interests in its composition fall on a rare-earth metal neodymium, whose natural deposits are extremely rare in nature. Most of them fall on China, they are still in several countries, including in Russia.

Before making neodymium magnets, manufacturers create forms for them from sand. Then, the tray with forms are glued with gas and are thermal processing, because of which the sand hardens and retains future outlines of the metal blank on its surface. In these forms, a hot metal will be placed later, from which, actually the necessary products will be obtained.

Now let's look at how the neodymium magnet make. In contrast to ferromagnetic products, the metal does not melt here, but sins from a powder mixture placed in an inert or vacuum medium. Then the obtained magnetoplast is pressed with simultaneous exposure to it electromagnetic field of a certain intensity. As we see, even at the initial stage of production, it is noticeable that the question of how to make neodymium magnets at home, sounds inappropriate. Operations and equipment used are too complex. Creating such conditions at home is hardly possible.

After the billets are getting out of the forms, they are machined - thoroughly polished, then their firing is performed to improve the coercive force of products.

Finally, we approach the last stages that will help finally answer the question of how neodymium magnets make. The sintered ndfeb alloy is re-finished on the machine by means of a special tool. When working, the cooling lubricant is used to exclude overheating or powder ignition.

A protective coating is applied to the magnets. This is due, firstly, the fact that the sintered metals are quite fragile and they need to be strengthened, and, secondly, the metal will be protected from corrosion processes and other exposure to the external environment. So manufacturers are concerned about how to make a neodymium magnet more durable and durable. The coating can be copper, nickel, zinc. At the last phase of the production process, magnetization is applied by means of a strong magnetic field. Further - they are sent to the warehouse, and from there to buyers.

So, after we have more or less in detail reviewed the production process, it became clear that, probably, it is not necessary to seriously wonder how to make a neodymium magnet at home. " After all, this requires not only the presence of certain knowledge, but many of the most complex aggregates.

To understand how to increase the power of the magnet, you need to figure it out in the magnetization process. This will happen if the magnet is located in an external magnetic field opposite to the source. The increase in the power of the electromagnet occurs when the current supply increases or the winding turns are multiplied.

You can increase the magnetum of the magnet using a standard set of necessary equipment: glue, a set of magnets (you need a constant), current source and insulated wire. They will be needed to implement those methods for increasing the power of the magnet, which are presented below.

Strengthening with a more powerful magnet

This method is to use a more powerful magnet to enhance the source. For implementation, one magnet should be placed in the outer magnetic field of another with a greater power. Also, for the same purpose, electromagnets are used. After keeping the magnet in the field of another, there will be a strengthening, but the specificity is in the unpredictability of the results, since for each element such a procedure will work individually.

Strengthening by adding other magnets

It is known that each magnet has two poles, and everyone attracts the opposite sign of other magnets, and the corresponding - does not attract, only repels. How to increase the power of the magnet using glue and additional magnets. Here is supposed to add other magnets in order to increase total power. After all, the more magnets, that, accordingly, there will be more power. The only thing to take into account is the attachment of the magnets of the eponymous poles. In the process, they will be repelled according to the laws of physics. But the task is to bonding, despite difficulties in physical terms. It is better to use glue, which is designed to glue the metals.

Gain using the Curie point

In science there is a concept of point Curie. The gain or loosening of the magnet can be produced, heating or cooling it relative to this point itself. So, heating above the point of Curie or strong cooling (much lower it) will lead to demagnetization.

It should be noted that the properties of the magnet when heating and cooling relative to the Curie point have a jump-like property, that is, having achieved the correct temperature, its power can be strengthened.

Method number 1

If the question arose how to make a magnet is stronger if its force is controlled by an electric shock, then it is possible to make it possible by increasing the current, which is fed to the winding. Here is a proportional increase in the power of the electromagnet and flow. The main thing, ⸺ gradual feed, to prevent one's brand.

Method number 2.

To implement this method, it is necessary to increase the number of turns, but the length should remain unchanged. That is, one or two additional series of wires can be made so that the total number of turns has become greater.

This section discusses how to increase the power of the magnet at home, for experiments can be ordered on the Melmagnets website.

Strengthening an ordinary magnet

Many questions arise when ordinary magnets cease to perform their direct functions. This often occurs due to the fact that household magnets are not so, because, in fact, they are magnetized metal parts that lose properties over time. Strengthen the power of such parts or returns them the properties that were initially impossible.

It should be noted that the magnets to attach them, even more powerful, does not make sense, since, when they are connected in reverse poles, the external field becomes much weaker or neither is neutralized.

This can be checked using the usual household mosquito curtain, which should be closed in the middle using magnets. If the weak source magnets top to attach more powerful, then as a result of the curtain, it will generally lose the properties of the connection by attraction, because the opposite poles neutralize each other's external fields on each side.

Experiments with neodymium magnets

Netomagnet is quite popular, its composition: neodymium, boron, iron. Such a magnet has high power and is distinguished by resistance to demagnetization.

How to strengthen neodymium? Neodymium is very susceptible to corrosion, that is, quickly rust, so neodymium magnets cover nickel to improve the service life. They also resemble ceramics, they are easy to break or split.

But trying to increase its power with an artificial way there is no point, because it is a permanent magnet, it has a certain level of force. Therefore, if you need to have more powerful neodymium, it is better to purchase it, given the necessary power of the new.

Conclusion: The article considers the topic, how to increase the power of the magnet, including how to increase the power of a neodymium magnet. It turns out that there are several ways to increase the properties of the magnet. Because it is simply the magnetized metal, to increase the strength of which is impossible.

The most simple ways are: with the help of glue and other magnetics (they must be glued with identical poles), as well as more powerful, in the external field of which the original magnet should be located.

Methods for increasing the power of the electromagnet, which include additional winding with wires or enhancing current flow. The only thing to take into account is the strength of the current flow in order to safety and the safety of the device.

Conventional and neodymium magnets are not able to succumb to an increase in their own power.
