Abstract:
A method for magnetizing a superconductor element, comprising the steps of:cooling the superconductor element; andmagnetizing the superconductor element, comprising:a first step of applying a first pulsed magnetic field to the superconductor element by supplying a magnetizing coil with a pulsed current whose peak value is controlled beforehand, thereby causing the superconductor element to capture a magnetic field, andat least a second step of applying a second pulsed magnetic field to the superconductor element, thereby causing, after all of the at least second steps are performed, the superconductor element to capture an increased magnetic field in relation to the magnetic field captured after the first applying step,wherein an intensity of successive pulsed magnetic fields applied to the superconductor element is equal to or less than that of a preceding pulsed magnetic field.
