摘要: The phenomenon of hysteresis in magnetic materials has been widely studied for many decades and several models have proposed to find good approximations this phenomenon. simulation presented paper describes a cylindrical type II superconductor small aspect ratio. A fundamental approach, using energy minimization, applied by which the demagnetization effects are naturally included. comparison made between critical current derived from magnetization Bean's formulation infinitely long cylinder that short used our calculations, it indicates how error Bean model can be minimized.
