Working principle of laminated iron core:

According to the law of electromagnetic induction, when an alternating current passes through a coil, the iron core will generate an alternating magnetic field. Due to the high magnetic permeability of silicon steel sheets, they can concentrate and guide magnetic fields, allowing the magnetic field to interact more effectively with the coil and improve electromagnetic conversion efficiency. The insulation coating can prevent the formation of conductive paths between silicon steel sheets, reduce eddy current losses, and ensure stable operation of the iron core under alternating magnetic fields.
