As I understand it, flux pinning is when a material becomes a superconductor in the presence of a magnetic field, say from a permanent magnet, and the lines of flux from the permanent magnet are trapped inside the superconductor causing the superconductor to be held ("pinned") at a fixed distance from the magnet. Ok. My question is this: Let's say I have a cube of superconducting material and 6 cube-shaped permanent magnets. I set up the permanent magnets on a rigid structure in such a way that the cube of superconducting material is in the center and each side of the superconductor has a permanent magnet next to it, with a small gap (let's say 1 mm). So, once I set this up (the superconducting material isn't a superconductor yet), I hold the superconducting cube in the very center with tweezers (at a fixed distance of 1 mm from each magnet), then I cool down the whole thing and the cube becomes a superconductor. Now for the real question: am I correct in assuming that the magnetic field of the permanent magnets surrounding the superconductor will become pinned in such a way that, when I remove the tweezers, the superconducting cube in the center will stay 1 mm from all of the magnets, effectively holding the superconductor in the center no matter how I tilt or otherwise move the entire device. In other words, will the superconductor become locked in the center of the magnets?
