WebThe Meissner effect (or Meissner–Ochsenfeld effect) is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state when it is cooled below the critical temperature. This expulsion will repel a nearby magnet. The German physicists Walther Meissner and Robert Ochsenfeld discovered this phenomenon in … WebThis effect is known as flux quantization. A situation like that just described arises in the motion of electrons in a superconducting ring through which a magnetic field passes. …
WebSupporting: 1, Mentioning: 5 - The critical temperature in a superconducting ring changes periodically with the magnetic flux threading it, giving rise to the well-known Little-Parks magnetoresistance oscillations. Periodic changes of the critical current in a superconducting quantum interference device (SQUID), consisting of two Josephson … WebThe observation that the magnetic flux in a hollow superconducting cylinder is quantized in units of hc/2e has confirmed Fritz London's prediction that superconductivity is a …
