My position is that coiling the wire reduces skin effect to negligible, and that adding a core with mu of 2000 renders skin effect undetectable. I would like references, on either side of the question, especially those with illustrations.
No permanent magnets, or other field generation, Just the magnetic field, resulting from the current in the loop, is there a force on a flexible conductor? If so, does the force tend to open the...
