摘要：

Governing equations to describe electromagnetic phenomena in superconductors were derived by using Helmholtz theorem. The Meissner effect, which is common to type-I and type-II superconductors, is treated by introducing the magnetization vector 'M'. The current flow due to flux invasion into the superconductor, which is a particular phenomenon in the type-II superconductor, is evaluated using current vector potential 'T' together with constitutive equations expressing critical state models. Numerical results based on a two dimensional FEM code, showed excellent agreement with analytical solutions.
