Levitating & spinning superconductors! #shorts #fyp

Transcript

look at this this is a super compactor okay so what just piece of ceramic man-made material if I to liquid nitrogen temperature it will become a superconductor it will conduct electric current without any resistance inside this plastic enclosure I have a superconductor I press it against this magnetic track that our students built watch I press it against it is limitating and I can put something on the way look at this it is floating because this tiny tiny magnetic vortices penetrating this superconductor like tiny tiny microscopic fingers and they keep this superconductor in place that's why it goes round around this track
