The poles on a spherical magnet are at the positive side and the negative side.Just like that of our earth which has both a north and south pole. The magnetic field is described as loops going from the north pole too the south pole, just as a normal bar magnet would behave. However a spherical electromagnet can be made such that the poles are constantly changing and never in one spot for too long The answer to your question is impossible without more information or experimentation with the magnet. An easy way to test which is north and south is to hang the magnet on a string and then positively or negatively charge a nylon rod by rubbing a material on it and hold it near all the sides. One side will be repulsed then that would be the sign of whatever the rod is charged with. I hope that this long winded answer helps. As a note north is positive and south is negative.
