The magnetizer is direct current. Magnetizing machine is also called impact magnetic machine, magnetic machine. Its job is to apply magnetism to the magnet. The magnet is just produced and does not have magnetism, and must be magnetized by the magnetizer before it can be magnetized. The capacitor is first charged with a high DC voltage and then discharged through a coil with very little resistance. The peak value of discharge pulse current can reach tens of thousands of amperes. This current pulse creates a strong magnetic field within the coil, which permanently magnetizes the hard magnetic material placed in the coil.
The peak pulse current of the magnetometer container is very high, which requires the capacitor to withstand the impulse current.
