Well, superconductors resist magnetic lines of force from moving through it,this a bit diff, parts of the superconductors outer layer allow mag field but the core does not, hence crunchy.

I always thought that superconductors simply mirrored magnetic fields because they have zero resistance to electromagnetic radiation. Since when did quantum factors become involved?

This site has a neat little explanation;

As I said in the other thread:

You gonna get your labtech to order the gear after half term ?

:lol:

That could be an idea.....My mate made an Yttrium barium copper oxide superconductor at Uni. It was really low tech - just mixing up the ingredients and baking in the oven with a measured flow of O2 thrown in...

:think:

Me and my lab tech just knocked up this video to help my little year 7 class build these high tech electron KE to soundwave transference devices;

Only a small step to creating superconductors eh?

They should make a mini-hovercraft for that circle, with a tiny propellor moving it around :D

Oh, and when will these things work at 300 Kelvin?
