A metal plate is getting heated. It can be because

A

a direct current is passing through the plate.

B

it is placed in a time varying magnetic 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
The heat produced in the metal plate can be due to direct or alternating current and when the plate is placed in a time varying magnetic place, then also due to eddy current it will get heated.
