Quantum Levitation

An unidentified member of the university’s Superconductivity Group School of Physics and Astronomy shows off the quantum locking effects of a magnet that’s been super cooled with liquid nitrogen.

When a material is in its superconducting state — which involves very low temperatures — it is strongly diamagnetic. This means that when a magnetic field is externally applied, it will create an equally opposing magnetic field, locking it in place. Cool:
