Is it possible to measure the grade of a magnet? Even if you 'only' have a gaussmeter?
It is interesting to know, since neodymium magnets are expensive and it would be nice to know, if you get what you pay for.
In this video I attempt to confirm the grade on some magnets before trying to determine the grade of a questionable, cheap N52 magnet.
Let's see what it takes to determine the grade of a magnet - or at least get an indication of it...
