There are no parasitics, it's a topological phenomenon. AGI will solve this problem though and I know how to do it for $80B. Tell your friends and maybe we can get VCs to finance AI for electrical engineering. Solving electrical engineering requires a lot of money. "Electromagnetic Theory and Computation" is a good reference on topological properties of electromagnetism but AGI would already have the relevant knowledge and agree with me. Homology and Cohomology would be standard training for all future AGI dealing with electricity.
