Thanks for the answer. I guess I am still a bit confused. I agree that a table would not need any energy to hold the SC up, but there would be physical contact between the table and the SC. My muscles would have to expend energy to hold the SC above the table, or if I suspended the SC above...
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...
