Tel-Aviv University demos quantum superconductors locked in a magnetic field.
It's called Meisner effect:
Basically, the magnetic field is bent around a superconductor (instead of going through it as in normal metals). So a superconducting magnet can be levitated or suspended on a track of permanent magnets, since it follows the expelled field lines. Also works the other way around, with a permanent magnet on a superconductive surface
Cool demo, in uni we used a supercooled metal ring and electromagnet to make a gun which fired the ring across the lecture theatre.
now that's the stuff we should be doing instead of fighting with another country. Great FIND ! this guy should be getting millions. I think this is the first example of quantum locking i have ever seen...
Science rocks!!!! as usual.....
