There are two coils A and B as shown in ...

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

A

there is a constant current in the counter clockwise direction in A.

B

there is a constant current in the clockwise direction in A.

C

there is a varying current in A.

D

there is no current in A.

Text Solution

Verified by Experts

The correct Answer is:
d
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.
