Abstract

The magnetic suspension of a high-Tc Bi, Pb-Sr-Ca-Cu-O superconductor beneath a ring-shaped permanent magnet was examined by means of an improved magneto-balancing method at 77 K. Both the experimental values of the suspending position and the force exerted upon the superconducting specimen were in good agreement with those calculated from the magnetization curve of the specimen and the magnetic field map of the used permanent magnet. The magnetic suspension was thus clarified to be due to the Meissner effect, not due to the well-known pinning effect.
