PROBLEM TO BE SOLVED: To provide a lifting magnet control system which is mounted on a vehicle equipped with a lifting magnet and capable of attracting a cargo by the lifting magnet even when the engine speed is low. SOLUTION: The lifting magnet control system 2 is mounted on a vehicle equipped with a lifting magnet 10. The lifting magnet control system 2 comprises a synchronous AC generator 4, a magnet driving circuit 31 including a DC conversion unit for converting the AC power supplied from the synchronous AC generator 4 to the DC power and an H bridge circuit unit for supplying the DC power to the lifting magnet 10 by controlling the direction of the DC power, a bridge driver 32 for driving a plurality of transistors, and a battery 5 for supplying the DC power supply voltage V<SB>BAT</SB>to the bridge driver 32.
