OK, some analysis of Maxwell’s equations on a twist ring show promise, it should work–but it’s going to be a lot harder to prove it mathematically than I hoped. The key is to show that there is a 1/r^3 magnetic field generated by the twist. The twist will drag an E field around, inducing a changing E field in a ring about the ring, making it a much more complex field equation than I was hoping for. This dragged E component handily causes a B field that matches that of a small current loop, and should have a radial partial derivative that goes as 1/^r3. But–uggh. The math! I’ve got my work cut out for me…
