Solution
The correct option is B South
The magnetic south pole of the earth's magnetic field is at the geographic north pole and the magnetic north pole is at the geographic south.
The magnetic field lines flow from north to south outside the magnet and south to north inside the magnet.
When the north pole of bar magnet points geographic north , the null points are formed on the equatorial line at two points where magnetic field lines from the bar magnet (directed north to south), are cancelled by the magnetic field lines by the earth's magnet .
