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 [NCERT Exemplar]
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 counterclockwise direction in A.
