Vedclass · Answer

(A) Null points are the points where the magnetic field due to the bar magnet is equal and opposite to the horizontal component of the Earth's magnetic field $(B_H)$.When the north pole of a bar magnet points towards the geographic North,the magnetic field lines of the magnet on its equatorial line are directed from the magnetic North pole to the magnetic South pole (i.e.,from North to South).Since the Earth's horizontal magnetic field $(B_H)$ is directed from geographic South to geographic North,the magnetic field of the magnet $(B)$ on the equatorial line opposes $B_H$.Thus,the null points $N_1$ and $N_2$ are located on the equatorial line of the magnet when the north pole of the magnet points towards the geographic North.

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