Electromaglev-levitation data for single and multiple bulk YBCO disks

This paper presents recent results of a small-scale electromaglev experiment, focusing on lift data for YBCO samples of a 30-mm/spl phi/ single disk and multiple disks comprised of seven, six, and three 10 mm/spl phi/ disks. The data are interpreted with the zero-order theory developed earlier. A phenomenological scaling law that correlates lift forces among samples has been developed.
