What is magnetic charge? How can it be explained on the basis assumptions on of Maxwell's equations?

There's no magnetic charge in Maxwell's equations as we know them. To add a magnetic charge, analogous to the electric charge, you'd change the equations in two ways:
1. Instead of setting the divergence of magnetic field B
to zero, it would be some (units-dependent) constant times the magnetic charge density.
2. The curl of the electric field E
would have an extra term, some (units-dependent) constant times the magnetic current density.
That would make a nice symmetrical set of relations between electricity and magnetism. However, so far no one has found any magnetic charge or magnetic current.
