Simple Inexpensive DIY Magnetic Polarity Tester

Magnetic Tester Hall Effect Sensor

DIY battery powered Magnet Pole Tester. Detect the North and South Poles of a magnet.

I lost the AMY6 Magnet Tester I purchased on Amazon so I decided to just build one. A circuit diagram is in the video.

 

If you don’t want to build your own Magnet Polarity Detector with hall effect sensors you buy buy these inexpensive polarity detectors from Amazon.  I own both and they cant be beat for the price.

Magnetic Polarity Detector Trial Test

Trial test of a Magnetic Polarity Detector using a hall effect sensor (APX9141) and indicator LEDs. This is just a test before I build a battery powered pen sized Magnet Pole Tester. I lost the AMY6 Magnet Tester I purchased so I decided to just build one. A circuit diagram is in the video.
