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 space varying magnetic field, but doesn't vary with time.
D. an alternating current passing through the plate
E. it is placed between the pole pieces of a magnet

Choose the correct answer from the options given below:

A, B and D Only

The correct answer is Option (4) → A, B and D Only

(A) When a direct current (DC) passes through a metal plate, the resistance of the plate causes it to heat up according to joules law.

(B) A time-varying magnetic field can induce currents in conductor, which can cause heating.

(D) When an AC current passes through the plate, it also generates heat due to resistance of plates.
