This is probably a very naive question, but I am trying to wrap my head around the concept of flux pinning (quantum locking).
For all intents and purposes, it appears as if a superconductor suspended above a magnetic field is defying gravity. I understand that there is no work being done (as there is no movement) but if I was to extend my arm and hold up a 100g superconductor, I would have to expend energy to prevent gravity from pulling it down. If a 100g superconductor is suspended above a magnet, is there energy associated this is 'anti-gravity' effect?
Thanks,
J
