A metal plate is getting. 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
When a metal palte is getting heated, it may be due to the passage of directed current, alternating current or even induced current through the plate. As time varying magnetic field produces induced current in the plate, therefore, choies (a), (b), (d) are correct.
