Where Can I Purchase a Superconductor?

[py0rchemist]

I need to buy a superconductor for a simple project. I'm only demonstrating how it floats on a magnetic track.

Where could I find a superconductor that will work under Liquid Nitrogen's temperature, and is around 2-5 inches in diameter?

I've only been able to find very tiny (about .5-1inch) superconductor kits, so far.


Can anyone help?

2-5 inches is large for HTC - I've only seen cm pieces.
I don't know if you can make such large pieces, they would certainly be expensive and probably difficult to cool without breaking.

I know I've seen them in various videos online, but what if your saying is true, they must have been made just for that demonstration...

why don't you buy some wire from american superconductor. they are located in devens, ma and manufacture the type2 superconducting wire that can retain superconductivity at high magnetic fields and high temp. that's the stuff they used to build the supercollider in switzerland. comes in really long rolls. i bet you could get some scrap pieces if you rummaged around in their trash.
