How does a magnetic monopole break time reversal symmetry?

I read in the article on the magnetic monopole in the German Wikipedia that the path of an electrically charged particle in the field of a magnetic monopole breaks time reversal symmetry. This means, …

Vector potential field for a hypothetical magnetic monopole

This is a mathemetical question with perhaps a physical interpretation. I would like to solve the equation: $$ \vec{\nabla} \times \vec{A} = \frac{1}{r^2} \hat{r} \tag{1}$$ using spherical coordinat …

Magnetic monopole and quantisation of angular momentum

I read chapter 6.12/6.13 in J. D. Jackson's Classical Electrodynamics about the magnetic monopole and a certain detail is confusing me. First in a semiclassical consideration of a magnetic monopole, …
