When the `N`-pole of a bar magnet points towards the south and S-pole towards the north, the null points are at the

A

magnetic axis

B

magnetic centre

C

perpendicular divider of magnetic axis

D

N and S-poles

Text Solution

Verified by Experts

The correct Answer is:
A
If the north pole of a magnet points south , the fields of the magnet and the earth will point in opposite directions along the axis of the magnet , so two neutral points are obtained which are equidistant from the magnet on its axis.
