A high gradient magnetic separator comprises a separating ring as well as a driving device, an ore feeding device, a refined ore unloading device and a refined ore collecting device of the separating ring, wherein the separating ring comprises a rotating ring, a magnetism gathering medium pack, an upper magnet yoke, an upper magnet, a lower magnet yoke, a lower magnet, a left magnet yoke, a right magnet yoke, and a magnetizing-demagnetizing device capable of magnetizing and demagnetizing the upper magnet and the lower magnet and comprising a magnetic coil and an excitation power supply. The utility model skillfully combines a permanent magnet with the excitation power supply so as to form a background magnetic field of the magnetic separator, and effective ore separation can be conducted by conveniently magnetizing the upper magnet and the lower magnet and then withdrawing the excitation power supply according to a requirement value of the background magnetic field during the work, and meanwhile, the problem
