Magnetic pole detector (pure hardware)

Overview

The magnetic pole detector (pure hardware) used to detect the polarity of magnetic poles can detect the polarity of magnetic poles. The sensitivity is adjustable and can be adjusted to the highest level to detect the earth's magnetic field. It is recommended that the potentiometer be replaced with a 3296 multi-turn potentiometer. If the sensitivity is not high, the potentiometer in the picture can be used. When there is no magnetic field or the magnetic field is weak, both LED lights will not light up. The red light will be on near the N pole and the blue light will be on near the S pole. Of course, this depends on how you weld. Demo video: https://www.bilibili.com/video/BV13741167Hb
