In the case of electromagnetic field with monopols, the concept of magnetic charges in the SU2 gauge theory with the Higgs field and that in the global U1 gauge theory are shown to be equivalent mathematically. The method of description of electromagnetic fields with magnetic charges in terms of U1 gauge theory and the variational method for the derivation of the world lines of charged particles is considered.

We prove that a gauge field can be determined locally by the field strength together with its gauge derivatives up to a certain order. It is shown, however, that in the non-Abelian case, two non-analytic gauge fields may be non-equivalent globally even when they are locally equivalent everywhere, no matter whatever the base manifold may be.
