The calculation with parallel turns implemented in the program only
works for stacked turns, that can simulate a single turn made with
a wide foil. It would be relatively simple to extend the program to
deal with spiral coils made with foil, or parallel wires, but this
is not implemented. I will see what I can do.

This is implemented.
