Superconductors that possibly work at room temp.

  1. ...magnetic field?? by Transcendent · · Score: 3, Insightful

    "For example, when the researchers put a magnetic field across a bundle at temperatures up to 400 kelvin (127 C), the bundle generated its own weak, opposing magnetic field. Such a reaction can be a sign of superconductivity."

    Correct me if I'm wrong, but I thought that all current carrying deviced generated their own opposing magnetic field.... even the wires going through most all buildings. The strenght of this magnetic field would allow us to calculate the resistance in the conductor, them stating that it produced a weak magnetic field doesn't prove much...
