Abstract
This paper presents an analytic model of the symmetrical magnetic levitation force between a point magnetic dipole and a flat non-ideally hard superconductor due to different field cooling processes. Yang and Zheng (J. Appl. Phys. 101 (2007) 113922) reported an updated frozen-image model which can give the hysteretic characteristic in the levitation force. But, their model is remarkably influenced by the external parameters and can not give the saturated feature of the maximum levitation force in some situations. We show a model which can give the features both hysteresis and saturation independent from the external parameters.
