Question

what is a eddy current? explain? ​

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.

Explanation:

Answer 2

Eddy currents :

(a) Observed first by Foucault in 1895.

(b) When a mass of a metal moves in a

magnetic field or when the magnetic

field through a stationary mass of

metal is altered, induced current is

produced in the metal.

(c) This induced current flows in the metal

in the metal in the form of closed loops

resembling whirlpool or eddies.

(d) These are known as eddy currents or

Foucault current.

(e) Direction of eddy current is given by

Lenz's law.
