Quantum Levitation - Flux Pinning (Superconductors)

Several types of superconductor and neodymium magnet demonstrations showing Meissner effect, quantum levitation, and flux pinning. High-temperature superconductors exhibit the Meissner effect, where they expel magnetic fields when cooled below their critical temperature. Placing a small magnet above a cooled superconducting disc causes the magnet to levitate and placing a cooled superconductor above a magnetic field always the superconductor to levitate, demonstrating the complete expulsion of the magnetic field and the unique properties of superconductivity.
