Abstract

Suspension effect of a high-Tc Bi-Pb-Sr-Ca-Cu-O superconductor beneath the doughnut-shaped permanent magnet was examined by means of a improved magneto-balancing method at 77K. The observed values of both the suspension position and the force exerted upon the superconductor specimen were in good agreement with those calculated from the magnetization curve of the specimen and the intensity of the magnetic field of the used permanent magnet. Obtained results indicate that the origin of suspension effect in the present case is mainly due to Meissner effect, and a little different from the pinning force reported so far.
