Magnetic Levitation Using A Superconductor

magnetic levitation

Before demonstrating magnetic levitation this video shows a small magnet being cooled to a superconducting temperature using liquid nitrogen. Once cooled the superconducting magnet is shown performing magnetic levitation above a section of magnetic track as seen in the featured image.

Further in the video the magnet is kept longer at superconducting temperatures by building a container of  liquid nitrogen around it. It is then seen being whizzed along by hand while levitating above, clinging to the side and hanging below, a Möbius strip track plastered in neodymium magnets.

This Royal Institution (Ri) video also gives a good demonstration of eddy current generation slowing down a neodymium bar magnet falling through a copper pipe.

What Are Superconducting Magnets Used For Magnetic Levitation Made Of?

If you didn’t catch it in the video the little superconducting magnet is made from yttrium, barium and copper oxide (YBCO) and is super cooled using liquid nitrogen.
