Remotely changing superconductor levitation height

[jtmarmon]

Forgive me if some of my question sounds misguided or misinformed - I'm new to the flux pinning game.

I want to be able to modify the height of a quantum locked superconductor. My original plan was to levitate the superconductor over an electromagnet and modify the current to said magnet (increase the current for higher levitation height, decrease for lower). Further research has made it apparent to me that this won't work. Is there a way to change the levitation height of a superconductor short of mechanical interference within the system?

Yes, there is. A common method for controlling the levitation height of a superconductor is to adjust the temperature of the system. As the temperature increases, the critical temperature of the superconductor will decrease, which will reduce the amount of flux pinning and consequently reduce the levitation height. This can be done by either increasing the temperature of the superconductor itself or adjusting the temperature of the surrounding environment.
