Question:
I am doing an experiment about magnets and I need some information on the super cool magnet do you have any?


Replies:
Do you mean a superconducting magnet? A superconductor conducts electricity with no resistance, meaning a superconducting device in your home would not add to your electricity bill (except through the other equipment you might need to use it) - superconducting magnets have a few problems however - right now the only good ones work at very low temperatures (only a few degrees above absolute zero). New materials were discovered above 6 years ago that might work at higher temperatures, but I do not think there are any practical magnets made from them yet. You might be able to get some of these new materials from a standard scientific supply shop - check their catalog for "high temperature superconductors".
