The direction of the null point is on the equatorial line of a bar magnet, when the north pole of the magnet is pointing

A

North

B

South

C

East

D

West

Text Solution

Verified by Experts

The correct Answer is:
A

`N_(1)` and `N_(2)` are null points. And
`B_(m)=` horizontal component of earth's magnetic field
`B=` Magnetic field due to bar magnet.
