This is P!erCer, I just moved off google because it is so #&$^#& slow.
I got Maxwell SV, and it models magnetic fields very well (despite the many
crashing bugs). However, from what I am seeing, you can't really improve
much upon the simple cylinder wrapped in wire. I tried some really weird
designs, but they all turn out to have similar extension beyond the device.
No wonder there wasn't much on the internet about the shape. It doesn't
matter much at all.
