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 The magnet was held stationary for a few seconds with the North Pole in the middle of the solenoid and then withdrawn rapidly.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

Solution:

When the magnet will be moving out rapidly its speed will be higher from when it is pushed. Hence the deflection will be more.
