type 1 and type 2 superconductors
applications of superconductors

Meissner effect. ○. When a superconductor is placed in a weak external magnetic field, the field penetrates the superconductor only at. When the applied magnetic field is stronger than a critical value Bc, this increase in energy becomes higher than. 2∆. As a result, the electrons do not prefer MEISSNER EFFECT: (The flux exclusion). (Meissner and Ochsenfeld in 1933). भ a bulk superconducting material is cooled in a are magnetic field down to.If a small magnet is brought near a superconductor, it will be repelled becaused induced supercurrents will produce mirror images of each pole. Effect of magnetic field on superconductivity of fine-dispersed systems. The influence of the doping on the Mn site on the charge and orbital ordering 1.d Magnetism and Superconductivity in cuprates and ruthenates. This expulsion of external magnetic fields takes place for magnetic fields that are less than the critical field. Magnetic field greater than BC destroys the
