We present Part 2 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 DC magnetic field generated by a magnet system located underneath the floating sample. The 0th-order theory presen
