More amazing physics

(I did not produce this). It's another video from the superconductivity lab of the University of Oslo.

Because the superconductor is cooled in the presence of a magnetic field flux is pinned inside it. See

for another example and an explanation.

Why does the shit quality version have four million views?

@Bleenderhead It's the way youtube works. Justin Bieber has 167,988,629 views -the number of views is no indication of quality.

@Zantorc amen.

Well, aluminum and tin are superconductors, I think, but good luck getting it cold enough to be zero resistance. I think they might have used Bismuth strontium calcium copper oxide (BSCCO) which superconducts above the boiling point of nitrogen. I don't know where you can get that, or liquid nitrogen :)

where can i purchase one of these superconductors??? in my local hardware store???
