- 4ad 3y agoOnly type-I superconductors expel significant magnetic fields. Virtually everything you see on YouTube is a type-II superconductor. type-I superconductors require liquid helium. Also, only type-II superconductors can hover in a stable configuration near magnets. Flux pinning is required for that.
