Abstract

The angular momentum of a static electric charge–magnetic monopole is, in SI units, L=(eg/4π) â. Here, e and g are their respective strengths and â is a unit vector along the line from the electric charge to the magnetic pole. A simple derivation is presented of this well-known result. The derivation makes use of vector (and tensor) analysis; no actual integrations involving the electromagnetic field are involved.

Discussions

• A point electric charge $q$ and a point magnetic monopole $g$ at rest, separated by a distance $d$ , carry electromagnetic field angular momentum $$\mathbf{L} = \int \mathbf{r} \times (\mathbf{E} \tim [stackexchange, 5 points]
