Applications:

These ring magnets are diametrically magnetized, meaning the magnetic poles are located on opposite sides of the curved outer surface, rather than on the flat faces. This perpendicular magnetization makes them ideal for use on rotating shafts—perfect for sensor applications, magnetic couplings, or even small-scale electricity generation.
