It’s interesting. We don’t think much about electric and magnetic fields these days. There are many experiments one can do and the results are usually surprising. Even 150 years ago we knew essentially nothing about these things and every experiment was enlightening. The avid experimenter would have a collection of different kinds of magnets as well as copper wire, iron filings, AC generators, and bicycle wheels as a minimum. Electromagnetics involves a fair level of math competency for the theoretical stuff and it ends up in Einstein’s Relativity and some abstruse algebras. But, there is no substitute for lab bench experiment. Also, a turntable might come in handy. Tesla and Faraday are still nearly incomprehensible to most and that is what they did so they could visualize what is really happening: it’s not intuitive.
Now, consider two of these, with opposite flows... they form a double spiral, similar to the DNA spiral... basically forming a circuit.
RightWhale, would you like to join my Electric Universe Ping list? I'd be glad to have you. You seem to have an open mind.
