The north pole of a long bar magnet was ...

The north pole of a long bar magnet was pushed slowly into a short solenoid connected to a galvanometer. The magnet was held stationery for a few seconds with the north pole in the middle of the solenoid and then withdrawn rapidly.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

Text Solution

Verified by Experts

The correct Answer is:
D
Because of quick relative motion and direction of current also changes.
