Résumé

The authors present results of a comprehensive study, both theoretical and experimental, of an electromaglev ("active-maglev") system, in which a YBCO bulk sample is levitated stably in a direct-current magnetic field generated by a magnet system located underneath the floating sample. The 0th-order theory presented in part 1 is used to interpret experimental results of levitation stability, lift-to-weight ratio, and lateral stiffness for four YBCO samples: disk, annulus, the same annulus with a permanent magnet disk placed in the hole, and ring.
