To provide a lifting magnet control system capable of reducing energy consumption during an excitation period of a lifting magnet.

The lifting magnet control system 1 includes a generator 4, a power conversion unit 5 which converts power generated by the generator 4 and supplies it to a lifting magnet 2, and a control unit 7 for controlling the number of revolutions of the generator 4 so that the output power of the power conversion unit 5 is gradually reduced during the excitation period of the lifting magnet 2.
