The north and south poles are on the two 3 × 3 mm faces. Its very small size requires controlled handling and assembly fixtures to prevent loss, chipping, or uncontrolled attraction to nearby ferromagnetic components.
The listed pull force and surface field are reference values under controlled conditions. Air gap, target steel, contact geometry, surface finish, temperature, and pull direction all affect actual performance. Use the Magnet Pull Force Calculator for preliminary screening and the Neodymium Magnet Grades Chart when comparing N52 with other grades.
