Not read any of this thread yet, but it reminds me of a thought I had yesterday, I wondered if I could find a way to make a time varying magnetic field not cause induction, and my conclusion is that I could.
I could (at one point anyway) cancel the inductive field around a solenoid if I wound it over a toroid with the opposite inductive field but no detectable magnetic field.
