Axial magnetization places the north and south poles on the two flat circular faces. Confirm pole orientation before assembly, and account for air gaps, mating-steel thickness, surface finish, and temperature. Avoid impact because sintered neodymium magnets are brittle.
The listed pull force is a reference value under specific test conditions; actual holding force varies by application. Use our magnet pull force calculator for design estimates and compare material options in the neodymium magnet grades chart.
