I am aware of toroid cored inductors and that they produce no magnetic field outside or in the center of the toroid. Apparently a Rodin coil does produce a magnetic filed in the center but not the outside. Just by looking at the geometry this appears plausible. I have read some claims that the center magnetic field in a rodin coil is actually stronger than the field generated in a normal cylindrical coil of similar dimensions, although I have my doubts. Just curious if anyone has any knowledge of this and if it is so.
p.s. I know this guy is mostly a crack pot but his coil is interesting.
