Levitation Based on Magnetic Balance
Experiments with magnetic levitation led me to a completely new and startling effect. It is very surprising, but the magnet hovers without electronics or any sensors, only due to the rotation of another magnet. To repeat the experiment, you need to glue 4 magnets onto the nozzle from the engraver, position the poles as shown in the image.
The engraving machine must be turned on at almost minimum speed, otherwise the magnet gets too close to its rotating brothers and a collision occurs. With a decrease in speed, the magnet gradually moves away, and at a certain distance it begins to chatter in all directions until the connection breaks. If you think that this is the same way of levitation as the magnetic spinning top, you are wrong. The magnetic spinning top uses the method of a magnetic pit, and the ring magnet and the spinning top are directed to each other by the same poles, since they use the repulsive force to levitate. Levitation on superconductivity is also excluded here. I believe that in this method, the magnet levitates due to the rapid change of magnetic fields, as a result of which an alternating magnetic field is obtained and at a certain value of revolutions, magnetic equilibrium occurs. This is when one pole does not allow you to break away from the magnet, and the other does not allow you to approach it. And no matter what pole the magnet is turned to this field. I also noticed a dependence on the mass of the magnets, the frequency of revolutions and the strength of the magnetic field. The greater the mass and strength of the magnetic fields, the farther apart the magnets and the lower the speed, and vice versa.
I plan to repeat the experiment, but with large magnets and electromagnets.
I would like to hear the opinion of experts in this area. If you still have questions, in my experience, you can ask them in the comments.
