There are two coils \( A \) and \( B \) 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 counterclockwise. \( B \) is kept stationary when \( A \) moves. We can infer that
(a) there is a constant current in the clockwise direction of \( A \).
(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 \( A \).
