Question

A compass needle is kept in the centre of a bar magnet. Which of the following is true?
(a) It will point in the north-south direction.
(b) It will align itself along the length of the magnet with its N pole towards the N pole of the magnet.
(c) It will not point in any specific direction.
(d) It will align itself along the length of the magnet with its S pole towards the N pole of the magnet.

Answer 1

(d) It will align itself along the length of the magnet with its S pole towards the N pole of the magnet.

The north pole of the magnetic needle will be attracted to the south pole of the bar magnet and the south pole of the needle will be attracted to the north pole of the magnet. The needle will, therefore align itself with the length of the bar magnet with its S pole towards the N pole of the magnet.
