The effect of magnet moving speed on the relaxation of the maximum levitation force of YBCO bulk has been investigated. The experiment was carried out between a cylinder permanent magnet and a single-domain YBCO bulk, and the levitation force was measured using a self-made levitation force measurement system. It is found that the levitation force decreases with time after the gap distance between the magnet and YBCO bulk reduced to 2 mm and kept for the test. It is also found that the levitation force and its relaxation rate is different for different moving speed between the magnet and the YBCO bulk, and the higher the moving speed, the greater the relaxation rate of levitation force. However, the largest levitation force is obtained at an optimal speed, the higher the levitation force, and the faster the relaxation of levitation force.

“…A classical paper on the flux creep (Beasly et al, 1969) probably was the first to note that the total magnetic flux in superconductor remains unchanged for a long time after the small reversal of external magnetic field. This effect was studied later in more detail, and it formed the basis of the reverse methods for the stabilization of magnetization (Kwasnitza & Widmer, 1991, 1993 and levitation force (Smolyak et al, 2000(Smolyak et al, , 2002. The reversal leads to the internal magnetic relaxation (Smolyak et al, 2001) when the volume-averaged quantities do not change for a long time.…”
