Question

In the work here we adapted the idea of electric charges to magnetic fields and to calculate the Earth’s magnetic field component parallel to the work bench. This is equivalent of using magnetic monopoles. James Clerk Maxwell, the creator of modern theory of electricity and magnetism. Do his theories allow or disallow magnetic monopoles? List your sources and references.

In modern times, the magnetic north pole of a compass needle points towards geographic north. That means that the magnetic South pole is near the north pole. Do they actually coincide? Or, how close are they? Was this always the case? How do we know? List sources and references.
