Eddy physics
WebThe eddy currents create a magnetic field that exerts a force on the falling magnet. The force opposes the magnet’s fall. As a result of this magnetic repulsion, the magnet falls much more slowly. Going Further Eddy … WebIn electromagnetism, eddy currents (also called Foucault's currents) are loops of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the …
