Maxwell's equations can be slightly modified to account for monopoles;
changing a zero to a constant in the equation that describes magnetic
flux would deal with the monopole case.
However, since no one has ever observed a monopole (yet) it's believed
that the current formulation of Maxwell's equations is correct.

Actually, it's fairly easy to detect a monopole. The detector I heard
of is simply a loop of superconducting material. A monopole passing
through the loop would induce a current flow that would remain in the
loop after the passage of the monpole, unlike a dipole which after
passing through the loop would leave no net current flow.
So, Kyle, there's a simple experimental test for your alleged monopole.
I'm sure that consultation with a physicist would either allow you to
test your monopole or get you an explanation of why you don't really
have one. If you thought I was skeptical, try dealing with a real
