A magnet N-S is suspended from a spring and while at oscillates, the magnet moves in and out of the coil C. The coil is connected to a galvanometer G.
Then, as the magnet oscillates,
A. G shows deflection to the left and right with constant amplitude
B. G shows deflection on one side
C. G shows no deflection
D. G shows deflection to the left and right but the amplitude steadily decreases
