Abstract Webb7 sep. 2024 · Flux Pinning. While the effects of flux pinning may appear similar to the levitating magnets caused by the Meissner effect, the cause behind flux pinning differs in some ways. For flux pinning to occur, the superconducting material either needs to be very thin or it needs to be a Type II superconductor. dick whittington pantomime leeds
