Description: The grade of a magnet is important. It tells you how strong the magnetic material used for the magnet is. The higher the grade, the more expensive and powerful the magnet. However, measuring the grade is not easy. I have successfully tested it on 70x20 mm disc magnets, but what about my largest magnets: the monstrous Ø200x50 and Ø150x100 mm disc magnets? Let's find out!
