Question

Does anyone know of any suppliers or manufacturers of superconductors that work at normal temperatures?

Answer 1

There are no room temperature superconductors.

The highest Tc ever found is 138K. That is high enough to experiment with these materials using liquid nitrogen (77K). Which is a LOT easier and cheaper than having to deal with liquid helium.

If you really want to spend money on some toy kits:

For professional materials, see e.g.

But you need to understand that even high Tc wires are normally used at much lower temperatures. You will have to understand the theory of superconductivity to successfully use these materials, anyway.

Answer 2

A superconductor is a material that has no resistance. It is a ideal material rather than an actual material as superconductors don't exist. People have however reduced resistance to almost negligible values at extremely low temperatures. Superconductors are just not possible at room temp(this is what i presume you meant by normal temp)

Answer 3

First, define "normal temperature." If you mean "room temperature" the answer is no; no such material yet exists. The highest-temperature superconductors operate at temperatures no higher than about 138 K, which is easily reached using liquid nitrogen but is a long ways from "normal."

Answer 4

it incredibly is conceivable. On historical years, a superconducting cloth is carried out purely whilst that is temperature is absolute 0. Now there have been superconducting supplies at greater serious temperature. faster somebody can devise superconductors at even greater than room temperatures.

Answer 5

Not that I know of. I do know that, using experimental materials such as copper oxides, barium, lanthanum and yttrium, IBM's Zurich research lab in 1986 and the University of Houston in 1987 raised the temperature of superconductivity to -59 degrees Fahrenheit. As far as I'm aware no-one has got anywhere near to 0 degrees, let alone above that.

Answer 6

I didn't know such things excisted. A superconductor works when it is cooled down so there is no brownian motion to hinder the electron flow.
