9646 – Neodymium Magnet Block N52 L 40mm W 40mm x T 20mm

SKU 9646 is an N52 neodymium block magnet measuring 40 × 40 × 20 mm. Magnetized through the 20 mm thickness, this very high-force block is intended for experienced industrial users, engineers, OEMs, and procurement teams that require a large magnetic working face for fixtures, test equipment, separation concepts, prototypes, and heavy-duty assemblies.

Specifications

High-force handling and design notes

This is a very powerful, brittle magnet. Use controlled handling methods, keep hands and body parts clear of pinch zones, and prevent the magnet from snapping into steel or another magnet. Impact can chip or fracture the magnet and can damage the coating.

The listed 213.85 lb pull force is a comparison value under defined direct-contact conditions, not a universal safe working load. Air gap, target-steel thickness, contact area, coating, surface roughness, temperature, and shear loading can materially reduce usable force. Use the Magnet Pull Force Calculator for preliminary screening and the Neodymium Magnet Grades Chart when comparing N52 with other grades.
