A theoretical analysis is presented for the critical state of an infinitely long type-II superconducting strip characterized by an arbitrary critical current density {ital J}{sub {ital c}}({ital B}). An analytical framework is developed, and numerical solutions are presented for the quasistatic current-density and flux-density profiles, as well as the hysteretic magnetization curves. The field dependence of the critical current density significantly affects the shape of the magnetization curves.
