Title: Cheap magnet strength meter.
Post by: CG on January 30, 2022, 02:19:48 pm

I made this awhile back, I can't remember if I posted it or not.
It's a magnet strength meter made from a clear plastic cassette tape box and a permanent magnet.
It measures relative magnet strength just so you can compare magnets and identify the poles.
It cost less than a dollar to make.
