On the Magnetic Properties of the Perfect Conductor and the Superconductor

Abstract

Since the discovery of the Meissner-Ochsenfeld effect, it has been believed that superconducting cannot be interpreted as a phenomenon of infin- ite conductivity. But it will be shown in this paper that a body of very large conductivity with a great number of electrons moving freely in random directions behaves itself in a magnetic field in the same manner as the superconductor. It will also be shown that the conduction electrons in a normal metal, in addition to the ordinary Landau's diamagnetism, may yield quite a different kind of diamagnetism
