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?
