Two coils, A and B are as shown in the 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:
there is a constant current in the clockwise direction of A
there is a no current in A
there is a varying current in A
there is a constant current in the counter clockwise direction in A
Answers (1)
Coil A must be carrying a constant current in counter clockwise direction. Because of that, when A moves towards B, current induced in B is counter clockwise direction as per Lenz’s law. The current in B would stop when A stops moving
