This is a tool for detecting the polarity of magnets and giving a rough indication of their strength based on the sensing distance.

I've used this unit in previous videos, and some of you wanted to see what was inside.

I don't recommend taking these apart, as it is quite destructive.

If you have a use for one of these then they are available from AliExpress and other online marketplaces:-

The cost should be around £6, and if you browse them then they may appear in the bundle deal section of their site.


If you enjoy my videos and wish to support the channel to keep it independent, you can do so by supporting me on Patreon. I release videos without adverts for critique and feedback on Patreon as soon as they have been made. I also release Patreon-only backstage videos when I'm working on shows.
