FredWalter:
I'm looking to buy a guassmeter. Anyone have any advice? Anyone have any experience with guassmeters that they'd like to post?

Paul-R:
There is a large demand for these. Maybge someone will express an opinion
on this inexpensive DIY design:

NB. Magnetism has direction as well as strength.

The above design will let you test the relative strengths of magnets/electromagnets.

However if you are trying to reproduce someone else's device then you'll want to know the absolute strength of the magnets/electromagnets used.

The is another device on the second page, or tests could be designed to calibrate the inexpensive device.

Since you came up with the idea, please design such a test.

If your method involves mailing a calibration magnet around to everyone, so they can calibrate their inexpensive devices, well... once you've paid to mail this magnet around, and screwed around with calibrating your homemade device, you're not spending all that much less than one of the cheap pre-made gaussmeters.
