How do superconductors work?
You are currently reading a thread in /g/ - Technology
I'm doing a research task on the theory behind superconductors and how they are able be set for practical use on maglev trains. I'm finding it difficult to understand some of the theory and why this phenomenon occurs. Any help is appreciated.

You need a charge to disengage the magnet, no such thing as a superconductor. So, they don't work.

Superconductors work by having 0 resistance, or very very close to 0. In all materials we know of this requires super cooling them, think cryogenic cooling, in order to stop the natural vibration of atoms. What this allows is an input electron to never have an unbroken path across the conductor, making this effectively have 0 resistance.
Learn some college physics and a little bit of electronic theory man.
Having 0 resistance allows you to effectively pump great amounts of electrical current through them without triggering the Joule effect (they won't get hot). Big currents = big magnetic fields that are able to make the maglev train levitate. Problem is, as someone posted before, that such superconductors work only at extremely low temperatures, even thou they are improving them by creating special alloys
