A magnetically levitated superconducting coil device, Mini-RT, has been constructed using a high temperature superconductor for the purpose of examining a new magnetic confinement scheme of high-beta plasmas. The floating coil is wound with Bi-2223 Ag-sheathed tapes, and it is operated in the temperature range 20-40 K. The excitation tests of the coil were carried out and the rated current was successfully achieved by overcoming many difficulties. The first magnetic levitation was realized for one hour and the plasma production was initiated.
