Hi @SylvesterOester, thanks for your contribution, that is great!

I updated the formatting to (a) make it compatible with sphinx-gallery, and (b) bring it a bit inline with other examples (e.g., fullspace instead of whole space).

It would be great if you could have a look and give your approval, you can find the rendered version here: https://empymod--155.org.readthedocs.build/en/155/gallery/fdomain/sil_biot_savart.html

Now, there is one thing that should have some more information: Biot-Savart, as you give it, is frequency-independent, is that right? And for empymod, you use f=83 Hz. How does that affect your result? How would it work for, say, f=1e-5 Hz or f=1e5 Hz? Does it always hold? How can that be? It would be great if you could add an additional paragraph about that (also to your thesis by the way.)

OK, I made some tests. As long as the frequency is low enough (say, below a few 10k Hz), there is not much change in this case. So while 83 Hz might look arbitrary, it doesn't really matter.
