Abstract

A new scheme is proposed, which can treat electromagnetic field of the type-II superconductor under transient temperature field. In the analysis, one of the critical state models, the Bean model was employed to determine the current distribution in the superconductors and effect of magnetic flux flow was also taken into account. We chose both low and high Tc superconducting materials. Numerical results indicate that the flux flow strongly affects the stability against the quench in both materials
