There are two coils A and B as shown in Fig A current starts flowing in \( \mathrm{B} \) as shown, when \( \mathrm{A} \) is moved towards \( \mathrm{B} \) and stops when A stops moving. The current in A is counterclockwise. B is kept
\( \mathrm{P} \) stationary when A moves. We can infer that

W
(a) there is a constant current in the clockwise direction in A.
(b) there is a varying cuiıent in \( \mathrm{A} \).
(c) there is no current in \( \mathrm{A} \).
(d) there is a constant current in the counterclockwise direction in \( \mathrm{A} \).
