Abstract
THE STARTLING transition of a metal into its superconducting state is revealed by the complete disappearance of electrical resistivity at low temperatures. Indeed, the current in a closed superconducting circuit can circulate forever without damping. Another fundamental property of the superconducting state was discovered in 1933 when Walther Meissner and Robert Ochsenfeld demonstrated that superconductors expel any residual magnetic field. Similarly, superconductivity can be destroyed by applying a magnetic field that exceeds some critical value.Keywords
