Sphere magnets are ball shaped magnets.

The poles of a sphere magnet

The so-called magnetic pole refers to the place where the magnetism is the greatest, that is, the place where the magnetic lines of induction are densest.
In fact, the earth can be thought of as a huge spherical magnet with two magnetic poles. These two magnetic poles are the places with the highest magnetic induction on the surface of the earth.
The distribution of magnetic lines of induction of spherical magnets is similar to that of the earth, and the magnetic poles are the densest places on the surface of magnetic lines.
