Use dangerous experimental supplies with caution. If it violates national laws and causes any safety issues and disputes, I have nothing to do with any consequences.
The electromagnetic coil is wound with an outer diameter of 28*20mm and an inner diameter of 28*8mm I-shaped inductor frame + 0.8 copper wire. The conduit uses a transparent acrylic tube with an outer diameter of 8mm and an inner diameter of 7mm.
Try to use MOS tubes with a withstand voltage of 60V or more and an overcurrent of 110A or more.
If the main power supply is below 30V, power can be taken from the main power supply. When it is greater than 30V, the fuse needs to be disconnected and a separate 12V power supply is used. The maximum voltage of the main power supply is determined by capacitors, MOS, PCB, etc.
