How to choose a magnetizer?

      The magnetizer is a simple device, it is actually an electromagnet with very strong magnetic force, and then equipped with many iron blocks of different shapes as additional magnetic poles, so that it can form a close with the object to be magnetized The magnetic circuit. The working principle of the magnetizer is also very simple. First, charge the capacitor with a DC high voltage, and then discharge it with a coil with a small resistance. At this time, a strong magnetic field is formed in the coil, so that the hard magnetic material in the magnetic field is permanently magnetized. During this discharge process, since the peak value of the discharge pulse current is very high, the requirements for the performance of the capacitor to withstand the inrush current are also high.

     So, how to choose and match the magnetizer?

     1. Determine the magnetizing object, so as to determine the size of the magnetizing coil and the size of the magnetic field.

     2. The size of the magnetic field needs to be 3-5 times of jhc.

     3. Determine the size of the capacitor according to the size of the magnetizing coil.

     4. The appearance, reliability, and price of the equipment should be considered.
