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 The magnet was held stationary for a few seconds with the north pole in the middle of the solenoid and then withdrawn rapidly.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 solenoid
(c) at rest inside the solenoid
(d) moving out of the solenoid

Solution

moving out of the solenoid
Because the relative change in the value of magnetic field is maximum in this condition.

  Is there an error in this question or solution?
