Electromagnetic Field Momentum in Theoretical Magnetic Monopole-like Models

We show that some standard models of magnetic charge, the Banderet potential, the Dirac string potential, and the Wu-Yang fiber bundle approach, carry an electromagnetic field momentum in the presence of an electrostatic field. This electromagnetic field momentum suggests a violation of the center-of-energy theorem. We show that each of these monopole models also carry a hidden mechanical momentum, which saves the center-of-energy theorem.
