How could we detect a magnetic monopole, and why is it said that if a single magnetic monopole exists then all the electrons in the Universe must have the same rest mass?

I can't say I've ever done much thinking about either of these questions but magnetic monopoles could be detected easily enough assuming they exist, I reckon, because naturally they'd interact with electric circuits in a unique way (eg because they violate Gauss's Law, and the modification if magnetic monopoles exist has already been extensively studied).

I'd have to do a little digging to answer the second question.
If it's not too much trouble can you let me know where you heard it said that "if a single magnetic monopole exists then all the electrons in the Universe must have the same rest mass"?

It was Dirac who showed that if a single magnetic monopole exists, then the charge on the electron is quantised. Nothing to do with the mass.
Question Author
Thanks Flonska, the wikipedia article shows that it is electric CHARGES, not masses, that would be equal. I'd be grateful if Jim could dig a bit and explain monopoles in terms I can understand without resurrecting my meagre tensor knowledge.
Ah, thanks for clearing that up -- I was puzzling for a while about how the mass might come into it. Not that there may not be a link but if there were then it would be exceedingly complicated for sure!

I'll have to get back to you Rev.
