Abstract
A general critical-state model including the effects of both flux-line cutting and flux pinning is used to predict the internal-magnetic-field distribution at the critical current of type-II superconductors subjected to parallel magnetic fields. The anticipated behavior is considered for specimens in the form of both slabs or strips and thin-walled cylindrical shells. Striking dependences upon the applied field angle are predicted for the direction of the electric field in slab geometry and for the magnitude and direction of the induced azimuthal current in cylindrical geometry.
