Materials
- Neodymium magnets diameter 15, thickness 5 mm - 8 pcs.
- Electric motor from the kitchen mixer
- Plexiglass
- Copper tube with a diameter of 6 mm
- Copper sheet
- Aluminum rim.

Instruments, used by the author.

Igor had long wanted to experiment with a heater based on neodymium magnets.

Very often on the Internet, there are homemade products in which a disk with magnets installed in it is used. With it, you can heat metal objects to very high temperatures. During disk rotation, Foucault currents or stray currents occur in the workpiece material. It is because of them that the metal is heated.


Also, some craftsmen make water heaters, even use them in heating systems.

Description of the device manufactured by the author.
Igor collected the simplest model to test these effects. He found a 350 Watt electric motor. He borrowed it from an old kitchen mixer.

Then, a plexiglass disk was fixed on the motor shaft, in the grooves of which I installed 8 neodymium magnets 15 mm in diameter and 5 mm thick. The polarities of the magnets must alternate, and the number of magnets must be even.




Test process.
An important point. The effectiveness of this device depends not only on the number and strength of the magnets, but also on the speed of rotation of the disk. The greater the speed, the higher the efficiency.


For the first experiment, Igor took an aluminum disk with a diameter of 100 mm. When you turn on the engine, and trying to bring the disk to the surface, it begins to push off. This is due to the Foucault currents induced in the disk. It turns out something like a magnetic pillow.

A second important effect is also observed. In addition to repulsion, the disk begins to rotate. And if you hang it over the magnets on a thread - then it turns into a gyroscope, and strive to fly to the side.Using this effect, it is possible to transmit rotation without contact to a flywheel, for example. You can also make models of "perpetual motion machines", which transmit rotation through the surface of the table.



Then Igor made just such a spiral from a copper tube with a diameter of 6 mm. With her help, he wants to test an experiment with heating water.


Inside the tube, he fills with water, and installs a temperature sensor.


The tube is located above the magnets, and turns on the engine. In just 20 seconds, the water inside the tube boils, and its initial temperature was only 23 degrees. Upon further heating, steam forms. This is the main part of the flow heater.



In the next experiment, Igor will heat just such a copper plate. The melting point of tin was reached after 15 seconds. Not every modern soldering iron is capable of this.



And the last experiment, with the preparation of fried eggs. Igor took just such a frying pan, and checked it with a neodymium magnet. It does not stick to the pan itself, but when tilted to the side, it does not roll instantly, but slowly slides along the surface, the effect of braking is obtained. And this means that the pan has the necessary properties for working with induction hobs.


In such a simple way, the author managed to cook fried eggs in 6 minutes.


So, the functionality of the device is proven, but where to use it?

Of course, heat can be obtained more efficiently with the help of a conventional heating element. But for heat transfer, or rotation in a non-contact way, these effects can be used. You can also use this device in water mills, windmills, and other sources of mechanical energy to generate heat.

Thanks to Igor for a simple but interesting device, and experiments with him!

All good mood, good luck, and interesting ideas!

I saw about concrete slabs with electric heating accidentally dropping it broke it said it was an old nichrome with about a millimeter it warmed up like a tile connected to 4 slabs a group so that it didn’t warm very much really connected to a 380 triangle and the belazes with electric motors were a movie unfortunately I don’t remember this development yet the USSR can be found on the Internet
Eh, you are just a naive person,

No no no!! I saw it myself !! Spin without any capacitors !!!
They simply hide from us !!!
And yet, I saw the technology that if you wrap up the heater in a concrete slab and sprinkle with stone crumb on top, then you can heat any room (with any heat loss!) With 250 watts in fierce winter. Because:
1. He, thanks to the crumb, the heat transfer area is very high.
2. It uses the effect of a Russian stove.
3. He is QUARTZ !!!
4. The heat from him is not simple, but ULTRA-RED !!!
Do not believe? Look for Quartz Heater Queries
They hide a lot of things from us !!!

Oh, you are just a naive person, 2 motors will not spin, because the losses are large, more than 50 percent. The maximum why they spin is because they are powered by a capacitor. It is necessary to set the electric motor of high power, and to regulate the speed, and if there are 4 of them, then there will be no sense at all, since the BG will eat more than 2 liters of gasoline, I guarantee this. It’s better to ride on compressed air, putting 4 cylinders under the hood and slightly modernizing the engine.At the same time, you will travel 100-120 km on compressed air, and charging cylinders with air will cost 200 rubles. Or on water. Such machines already exist, but there is only one problem - for some reason, the plants go bankrupt and close.
Have one of them stopped loading images on the site, or is it something with the site?
And I also saw in YouTube that if you connect two motors with shafts to each other, and spin - then one will be like a motor, and the other - like a generator, they will spin forever and the light from them burns for free ...))))
And I was convinced by one that he put an electric motor on each wheel on an old Zhiguli, carries a gas generator in the trunk, and drives faster and more passable than before (it’s 4 motors !!!!)))), while the consumption is 2 liter per hour !!!
It is a pity the photo / video could not be thrown off; his phone was just buggy .... But it is worth believing him, because he proved very zealously! Looks like bruises on my chest remained - so I hit the heel there!))))
Moreover, according to him, Belarusians discovered this effect long ago, and such bastards are silent !!! And they themselves have been doing it on BelAZ for a long time !!! (And it’s not at all because five hundred tons on rough terrain will turn any cardan into a pigtail and crush any gear teeth!)))))))

If the effect is used as a heater, then what will be the efficiency? It turns out that the electric motor power turns into thermal energy, 350W fried fried eggs in 6 minutes. Try to fry on a burner at 350 there it will take much more time.
And didn’t think of something like this with a circular heating pump? If this tube heats up in 20 seconds, then the pump then works around the clock. Boiling is not necessary there, enough time, the speed can be made one, fixed, which means that the volume of heating can be increased. This question will be much more relevant than scrambled eggs.
