Question

The cause of production of eddy current is the
(a) current flowing in a conductor
(b) current flowing in an insulator
(c) motion of a conductor in a varying
magnetic field
(d) motion of an insulator in a varying
magnetic field​

Answer 1

Answer:

Eddy currents are currents which circulate in conductors like swirling eddies in a stream. They are induced by changing magnetic fields and flow in closed loops, perpendicular to the plane of the magnetic field. ... Like any current flowing through a conductor, an eddy current will produce its own magnetic field.
