ABSTRACT:
An apparatus for observing a superconductive phenomenon is disclosed. In the apparatus, a cooling unit cools a superconductor having a threshold temperature at which the superconductor changes from the normal conductive phase to the superconductive phase, and a magnetic field is applied thereto. A current is supplied to the superconductor, and there are clearly observed a phenomenon on which an electric resistance thereof becomes zero at a threshold temperature thereof, a phenomenon on which the superconductor changes from the normal conductive phase to the superconductive phase at a threshold current to be supplied thereto, and a phenomenon on which the super conductor changes from the normal conductive phase to the superconductive phase at a threshold magnetic field to be applied thereto.
