A metal plate can be heated by

A

A direct current is passing through the plate

B

It is placed in a time varying magetic field

C

It is placed in a space varying magnetic field, but does not vary with time

D

A current (either direct or alternating) is passing through the plate

Text Solution

Verified by Experts

The correct Answer is:
A,B,D
A metal plate is getting heated when a DC or AC current is passed through the plate, known as heating effect of current. Also, when metal plate is subjected to time varying magnetic field. The magnetic flux, linked with the plate changes and eddy currents comes into existance which make the plate hot.
