High-Temperature Superconductivity

Like astronomers tweaking images to gain a more detailed glimpse of distant stars, physicists at Brookhaven National Laboratory have found ways to sharpen images of the energy spectra in high-temperature superconductors — materials that carry electrical current effortlessly when cooled below a certain temperature. These new imaging methods confirm that the electron pairs needed to carry current emerge above the transition temperature, before superconductivity sets in, but only in a particular direction.

Go dad!

@jenecomprends I have such a magnet, and so does any hospital that does nuclear magnetic resonance. They are cooled with helium, hence expensive. Tu comprends maintenant?

@jenecomprends then if there is no superconducting magnet, what is diagmagnetism that repells the earth's magnetic field?? do we have a metal that has diamagnet??

[makmegs]

please give me your knowledge...

@vosa135 As for what I know, there is no superconducting magnet. There is only a superconductor with zero resistance, which shows a meissner effect when there is a magnetic field applied to the superconductor. This means the magnetic fields are not going through the conductor but are "bounced off"...

Is it true that when you apply an electrical current directly to a superconducting magnet it begins to vibrate and creates a small amount of thrust?
