Background

The traditional magnetizing method of the magnet mainly comprises the following steps: direct current magnetizing, pulse magnetic field magnetizing and superconductive magnetic field magnetizing. D, direct current magnetizing: and D, electrifying direct current in the electromagnet coil to generate a magnetizing magnetic field. Magnetizing by a pulse magnetic field: the AC is converted into DC and stored in capacitor, which is then discharged instantaneously or by large-capacity transistor to generate strong pulse current in the sprint coil, so generating strong pulse magnetic field to magnetize the magnet in the coil. When pulse discharge is carried out, the pulse current within a few milliseconds can reach more than 100KA, the maximum magnetic field which can be provided by a common pulse magnetizing device is about 6-10T, and in principle, a permanent magnet material with the coercive force of 2400KA/m can be magnetized to reach saturation in a demagnetizing state.
