Answer:

Explanation:

The magnetic field lines of a simple magnet are shown in the picture below. They point from the north pole to the south pole. However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole.
