A general critical-state model including the effects of both flux-line cutting and flux pinning is used for calculating B-, J-, and E-field distributions during the approach to the quasisteady state of a type-II superconducting slab subjected to a parallel rotating magnetic field. Three initial magnetic configurations (diamagnetic, paramagnetic, and nonmagnetic) are considered. It is shown that, depending upon sample parameters and magnetic history, multiple-zone structures develop inside the superconductor. It is also shown that, regardless of the specimen's magnetic history, flux-line-cutting B consumption leads to a final state in which B has a diamagnetic profile near the surface of the specimen. The relation of these calculations to the pioneering experiments of LeBlanc and co-workers is discussed.
