Abstract

A generalized model for hard superconductors has been developed to unify all previous forms of the critical-state model. The magnetization versus applied-field curves generated from this model are shown to be physically consistent with the original Bean model. Other expressions of the critical current density can all be derived from this generalized critical-state model.
