How can we explain quantum locking with new electromagnetism? A situation where they "levitate" a superconductor above or below a strong permanent magnet and it seems to "lock" in place. I somewhat understand distintis simplified magnet model but whats going on with this example. Another example would be a levitating spinning magnet "locking" with another magnet. Youtubes sudanamaru has examples of this.

A superconducter has no resistance so the induced eddy currents are like a mirror of the magnet. You can still move the "stuck" superconducter in the magnetic field. But you need to give him a push. The eddy currents will always be the perfect match to the magnet, so it will stay in position.
No "quantum locking" needed. This can be explained with simple induction.
If you have a circular magnet, the conducter can spin without friction and levitate. There are also racetracks made with multiple magnets. Then you can push the superconducter and it will follow the track with no residtance.
I think Robert mentioned the induced eddy currents in a superconductor, but I'm not sure which video it was.
