There are two coils \( A \) and \( B \) as shown in the figure. \( A \) current starts flowing in \( B \) as shown, when \( A \) is
\( \mathrm{P} \)
moved towards \( B \) and stops when \( A \) stops moving. The current in \( A \) is counter clockwise. \( B \) is kept
W
stationary when \( A \) moves. We can infer that:
(1) there is a constant current in the clockwise direction in \( A \)
(2) there is a varying current in \( A \)
(3) there is no current in \( A \)
(4) there is a constant current in the counter clockwise direction in \( A \)
