These discs are “diametrically magnetized,” which means that the poles are located on opposite sides of the circular shape, not in the center of the circular flat surfaces like most disc magnets. The magnets will tend to want to line up side-to-side rather than stack on the flat surfaces. The unusual magnetization makes them an interesting disc to experiment with.
