Would magnetic charge (i.e., magnetic monopoles) be Lorentz invariant if it existed?

It is clear that Maxwell's equations in themselves permit magnetic charges but what would their relativistic properties be?

• what makes you think that they wouldn't be Lorentz invariant? – innisfree Jun 11 '15 at 17:38
