A method for optimizing electromagnets using a microcontroller control circuit is proposed. The microcontroller outputs a low-level signal for a certain duration after power-on, causing the electromagnet's coil to approach the power supply voltage. During this duration, the electromagnet is attracted. After this duration, a PWM oscillation wave is output, causing the MOSFET Q2 to continuously turn on and off. A pulse signal with a duty cycle is applied to the coil. The power consumption generated by the current flowing through the electromagnet's coil during the PWM oscillation wave output is less than that under a 100% duty cycle.
