Токи Фуко / Eddy current.

In this old school Soviet video (Russian language) you will learn about Eddy currents, which occur in conducting media when the magnetic field changes. You will see various experiments demonstrating the effects of Eddy currents, such as: - Falling magnets in tubes. You will learn how Eddy currents slow the fall of magnets in metal tubes and how they depend on the material, shape, and size of the tube. - Heating samples with Eddy currents. You will learn how Foucault currents convert electrical energy into thermal energy and how they are used for induction heating of metals. - Levitation of a magnet over HTSP ceramics. You will learn how Eddy currents in superconducting ceramics create a magnetic mirror that holds a magnet in the air. - Levitation of a solid ring. You will learn how Eddy currents in a metal ring prevent it from falling under gravity and how they depend on the temperature and velocity of the ring. - Interaction between a conductor and an electromagnet. You will learn how Eddy currents inhibit the movement of a conductor in a magnetic field and how they create their own magnetic field that counteracts the external one. After watching this video, you will be able to better understand the physical nature of Foucault currents, their causes, and effects. If you want to support - just like this content!
