A ceramic is bathed in liquid nitrigen and becomes "superconducting. At this point, the electrical conductivity of the substance increases substantially. Since a current generates a magnetic field, the superconductor become an elecromagnet. The traditional magnent is suspended above the superconducting magnet with just the right balance of gravitational attraction and magnetic repulsion,
did you get that as a kit? and where did you get the liquid nitrogen to cool the ceramic?
