Within the construct of the complete Kim-Anderson model for the critical-current density, we have calculated the initial magnetization curves and full hysteresis loops of type-II superconductors immersed in an external field H=H dc +H ac cos(ωt), where H dc (≥0) is a dc bias field and H ac (>0) is an ac field amplitude. We denote the maximum and minimum values of H by H A (=H dc +H ac ) and H B (=H dc -H ac )
