A friend asked me if there were any materials that would significantly transport a magnetic flux WITHOUT being attracted or repelled by the source of magnetism.
My quick response to this question was 'Not in my experience'. Like a switched reluctance alternator, energy must go into the rotor to force the switching ... so this kinda random question seemed physics-impossible to my mind just on it's face, but I caught myself wondering if some esoteric material off my beaten path might qualify for a yes answer ... as I have been surprised many times before for not being in full possession of the facts.
As expected, my search turned up nothing so I thought I would post this question here to my betters to see if my gut is on target and I haven't missed something.
Best regards,
B
