1 × 1 mm Micro Magnet Design Notes

This micro-scale magnet is intended for controlled precision assembly. Its small size makes part handling, orientation, adhesive placement, and dimensional stack-up especially important during prototyping and production. Use inspection magnification and containment practices appropriate for very small components.

The listed 0.11 lb pull force is a comparison value under defined contact conditions, not a guaranteed safe working load. Air gaps, target-steel thickness, coating, surface roughness, and shear loading can reduce usable force.

Use the Magnet Pull Force Calculator for preliminary screening and compare N35 with other grades in the Neodymium Magnet Grade Chart.
