Applied Magnets manufactures premium-quality N52 neodymium magnets engineered for exceptional performance, consistency, and reliability. Produced using advanced manufacturing technology and strict quality-control standards, these magnets deliver maximum magnetic strength for demanding applications.
This N52 neodymium cube magnet measures 1/2" x 1/2" x 1/2" and features a 1/8-inch center hole. Manufactured from neodymium, iron, boron, and other minor elements, it provides superior magnetic strength compared to N50, N48, N45, N42, N40, N38, and N35 grades.
With a pull force of 34 lbs and up, this powerful cube magnet is ideal for industrial, engineering, manufacturing, and automation applications. The magnet is specifically magnetized parallel to the 1/8-inch hole direction, allowing it to be integrated into specialized assemblies and magnetic systems requiring this pole orientation.
What Is a Neodymium Cube Magnet?
A neodymium cube magnet is a rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Cube magnets provide powerful magnetic strength in a compact symmetrical shape. Cube magnets with center holes are commonly used in custom assemblies, robotics, fixtures, automation systems, and engineering applications where mounting or alignment capabilities are required.
How Strong Is This Magnet?
This N52 neodymium cube magnet generates 34 lbs or more of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a BrMax rating of 14,800 Gauss, it offers maximum magnetic performance available in commercial neodymium magnets.
