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 counterclockwise. `B` is kept stationary when `A` moves. We can infer that

Answer

d

Explanation

Coil A ust 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.
