Design notes for this miniature disk magnet

Axial magnetization places the poles on the two flat circular faces. Account for assembly tolerances, air gaps, mating material, surface finish, temperature, and orientation. Avoid impact and flexing 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.
