Question

what is eddy current ​

Answer 1

Answer:

Eddy currents (also called Foucault's currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.

Answer 2

If a piece of metal is placed in a varying magnetic field or rotated high speed in a uniform magnetic field then induced current set up the piece are like wire pool of air, called Eddy currents.

Magnitude of Eddy currents (I) = -e/R

These are also called Foucault's current.

hope this helps u❤️
