In this paper we studied the flux motion in a high-[ital T][sub [ital c]] superconductor. For both field-cooled and zero-field-cooled cases, we numerically solved the flux motion equations and calculated various magnetizations [ital M]([ital t]) changing with time [ital t]. The scaling behavior of the magnetization is obtained. There is a kink in the magnetization curve that corresponds to the flux front reaching the middle of the slab sample. The self-organized critical state (SOC) is related to the early time of the flux penetration and the effect of temperature on the SOC is discussed.
