Two questions about this:

- How do you compute the "self-potentials" of the tiles?
- Your description is valid for a tridimensional problem. What
happens in an axisymmetrical problem, as in a typical Tesla
coil?

I was thinking about a similar approach, using circles (or toroids)
instead of tiles, but then realized that this is the axisymmetrical
problem, or at least something that should be equivalent.
