8109 – N45 Neodymium Block Magnet 1 × 1/4 × 1/8 in

SKU 8109 is an N45 neodymium block magnet measuring 1 inch × 1/4 inch × 1/8 inch. It is magnetized through the 1/8-inch thickness, placing the north and south poles on the two broad 1-inch × 1/4-inch faces. Its compact rectangular geometry suits sensors, closures, fixtures, prototypes, and OEM assemblies.

Block Magnet Design Notes

Through-thickness magnetization provides the largest pole faces on this block. Keep the magnet fully supported during assembly because sintered neodymium is brittle and can chip or fracture under impact, bending, or uneven clamping.

The listed 9.41 lb pull force is a comparison value under defined direct-contact conditions. Air gap, target-steel thickness, coatings, adhesive layers, surface roughness, and shear loading can reduce usable holding force.

Use the Magnet Pull Force Calculator for preliminary design estimates and the Neodymium Magnet Grade Chart when comparing N45 with other grades.
