| Outline of Final Research Achievements |
Superconducting technique is applied to the levitation system. Persistent current in superconducting coil and control current in copper coil are used for levitating object and controlling object, respectively. The system is composed of a superconducting coil, a copper coil, a levitated object, a photo sensor, a PID controller, and power amplifiers. In this paper, basic study on superconducting coil and solenoid coil, and the dynamic characteristics of levitated object are performed. As a result, it is found that the levitated object continues to levitate at a distance 9.0 mm for 15 s. This may be the first trial that superconducting coil is used for magnetic levitation.
