Q. The north pole of a long bar magnet was pushed slowly into a short solenoid connected to a galvanometer. The magnet was held stationary for a few seconds with the north pole in the middle of the solenoid and then withdrawn rapidly. The maximum deflection of the galvanometer was observed when the magnet was
A) Moving towards the solenoid
B) Moving into the solenoid
C) At rest inside the solenoid
D) Moving out of the solenoid
Explanation
(d) More rapid is the movement of bar magnet, more is the deflection observed in the galvanometer
