Question

There are two coils A and B as shown in figure a current
starts flowing in B as shown, when A is moved towards B
and stops when A stops moving. The current in A is counter
clockwise. B is kept stationary when A moves. We can infer
that
(a) there is a constant current in the clockwise direction
in A
(b) there is a varying current in A
(c) there is no current in A
(d) there is a constant current in the counter clockwise
direction in A

Answer 1

Answer:

Coil A must be carrying a constant current in counter clockwise directon . Because of that, when moves toward B, current induced in B is counterclockwise direction as per Lenz's law. The current in B would stop when A stops moving.
