That is, the superconductor 3 is placed in a refrigerant gas having a temperature below its critical concentration, a heater is placed near the superconductor, and the superconductor 3 is heated to the critical temperature based on the output of the rear end position detector 13. A non-superconducting state is set at the above temperature, and heating of the heater is stopped based on the output of the front end position detector 12 to bring the temperature below the critical temperature to a superconducting state. In this case, the flow supply device 11 is connected to the heater, and in the embodiment, the permanent magnet 5 is used as the magnetic member 4, but an iron plate, a copper plate, etc. are used, and it is later replaced by the superconductor 3. It may be fixed. Furthermore, by fixing the permanent magnet 5 in the embodiment so that it does not move, the cylinder 1
