## Description

- description: Magnetic refrigeration, utilizing the magnetocaloric effect, has seen
    various applications due to its theoretically high efficiency, including helium
    liquefaction at 4 K, hydrogen liquefaction at 20 K, and room temperature magnetic
    cooling. Generally, the magnetocaloric effect becomes more significant with stronger
    magnetic fields, so when a substantial cooling capacity is required, superconducting
    magnets are employed. Superconducting magnets are cooled by GM cryocoolers and
    require dedicated power supplies. Generally, the dedicated power supplies for
    superconducting magnets are large in size and expensive. In this study, a superconducting
    magnet system has been fabricated and operated with small switching power supplies
    rather than a dedicated power supply for superconducting magnet, to examine the
    feasibility and controllability of superconducting magnet operation.
