    摘要: A magnetic device which is highly durable, reliable, and safe without being damaged when a magnetic filed is applied. The magnetic device includes a cooling device having a cold head refrigerated by an effect of a cryogenic refrigerator, a magnetic field generation device configured to apply a non-stationary magnetic field on a magnetic body, and a cold head extension portion configured to thermally connect the magnetic body and the cold head. The cold head extension portion includes at least two members, one a low resistance member and the other a high resistance member having different resistivities. With this device, the eddy current generated in the cold head extension portion and the electromagnetic force produced in the cold head by the cold head extension portion are reduced.

    摘要: A cold head is disposed in an insulating container and cooled by a refrigerator. A superconductor is disposed in the insulating container, contacting the cold head, and is cooled to its superconduction transition temperature or lower by heat conduction. A magnetizing coil is disposed outside the insulating container for applying a magnetic field to the superconductor. Control is performed so that a magnetic field determined considering the magnetic field to be captured by the superconductor is applied. A pulsed magnetic field is applied to the superconductor a plurality of times. Each pulsed magnetic field is applied when the temperature of the superconductor is a predetermined temperature or lower. A maximum pulsed magnetic field is applied at least once in an initial or intermediate stage of the repeated application of pulsed magnetic fields. After that, a pulsed magnetic field equal to or less than the maximum pulsed magnetic field is applied. Pulsed magnetic fields are repeatedly applied while the temperature of the superconductor is lowered. A pulsed magnetic field is applied when the temperature To of a central portion of the superconductor is the superconduction transition temperature or lower and the temperature of a peripheral portion is higher than T0. The temperature of the entire superconductor is brought close to T0 to apply another pulsed magnetic field. The magnetizing coil faces at least one of two opposite sides of the superconductor to apply pulsed magnetic fields to the superconductor in its magnetization direction.
