Remove π in the defintion of charge #13

Closed leon-vv closed 1 year ago

leon-vv commented 1 year ago

Currently the numerical charge values are expressed as $\sigma / \pi \epsilon_0$. I think it would be semantically clearer if we expressed the quantity as $\sigma / \epsilon_0$. The reason is that the $\pi$ value only makes sense in cylindrical symmetry, but we need to implement more symmetries.

After some reflection I think $\pi$ is present also in the other symmetries. So for now it might be okay to leave it in. The corresponding magnetic charge should be represented as $\sigma/\pi\mu_0$
