SUPER CONDUCTORS Superconductivity is an electrical resistance[->0] of exactly zero which occurs in certain materials[->1]below a characteristic temperature[->2]. It was discovered by Heike Kamerlingh Onnes[->3] in 1911. Likeferromagnetism[->4] and atomic spectral lines[->5]‚ superconductivity is a quantum mechanical[->6]phenomenon. It is also characterized by a phenomenon called the Meissner effect[->7]‚ the ejection of any sufficiently weak magnetic field from the interior of the superconductor
