Quantum Levitation or Vortex Pinning Explained

In this video, I explain the effects vortex pinning of vortex pinning on levitating superconductors. Since it involves vortices with one quantum of flux, the effects I am explaining are also known as quantum levitation or quantum locking, because that sounds cooler. However, since it's just another vortex pinning effect, I'll refer to it as such. I'll start out by explaining the Meissner effect in type I superconductors. I'll then explain vortices in Type II superconductors, before showing that vortex pinning can lock a superconductor to a magnet...
