Electromagnetic Field Momentum in Theoretical Magnetic Monopole-like Models

TL;DR

This paper investigates electromagnetic field momentum in various magnetic monopole models, revealing hidden mechanical momentum that preserves the center-of-energy theorem despite apparent violations.

Contribution

It demonstrates the presence of electromagnetic field momentum in standard monopole models and uncovers hidden mechanical momentum that maintains fundamental energy conservation laws.

Findings

Magnetic monopole models carry electromagnetic field momentum.

Hidden mechanical momentum exists in these models.

The center-of-energy theorem is preserved through hidden momentum.

Abstract

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.
