The main image shows an axial (thickness-direction magnetized) 4-pole circular magnet with a 4-pole configuration on both sides. Its magnetic poles are located on the top and bottom surfaces of the magnet, rather than on the sides. It is primarily used in Hall effect sensors, smart home appliances, and similar products.
