ABSTRACT
Examines the levitation force between a permanent magnet and a bulk YBCO superconductor subjected to motion induced step in the magnetic field. Connection of levitation force with time; Interpretation of the rate of decay based on thermally activated flux creep; Relation of the levitated magnet force to the bulk magnetization of the conducting material.

    The effect of stopping the levitation force relaxation was observed upon reversal of the superconductor magnetization. A model of the internal magnetic relaxation in levitating superconductors is proposed, according to which both the magnetic moment and the force acting upon the sample are constant.
