  The Dirac approach to include magnetic charge in Maxwell's equations places
the magnetic charge at the end of a string on which the the fields of the
theory develop a singularity. In this paper an alternative formulation of
classical electromagnetism with magnetic and electric charge is given by
introducing a second pseudo four-vector potential, C_mu, in addition to the
usual four- vector potential, A_mu. This avoids the use of singular, non-local
variables (i.e. Dirac strings) in electrodynamics with magnetic charge, and it
makes the treatment of electric and magentic charge more symmetric, since both
charges are now gauge charges.
