(B) When a bar magnet is placed with its north pole pointing towards the geographic north,the magnetic field lines due to the magnet are directed from north to south outside the magnet. The horizontal component of the Earth's magnetic field $(B_H)$ is directed from geographic south to geographic north. At the equatorial line (broadside-on position) of the magnet,the magnetic field due to the magnet is directed from north to south,which is opposite to the direction of the Earth's horizontal magnetic field. At certain points on the equatorial line,the magnitude of the magnetic field due to the magnet exactly cancels the horizontal component of the Earth's magnetic field. These points are called neutral points. Therefore,the neutral points lie on the equatorial line,which corresponds to the east and west directions from the center of the magnet.

$A$ bar magnet is placed in the north-south direction with its north pole pointing towards the geographic north. In which direction from the center of the magnet will the points of zero magnetic field (neutral points) be located?
