Product Overview
Neodymium magnets are the world's strongest permanent magnets. Applied Magnets offers premium-quality N52 neodymium magnets manufactured to stringent quality standards using advanced production technology. These magnets deliver exceptional magnetic strength, consistent performance, and outstanding reliability for industrial, engineering, and commercial applications.
This N52 neodymium cube magnet measures 1/2" x 1/2" x 1/2" and features a 1/8-inch center hole running through the magnet. 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 high-performance cube magnet is ideal for demanding applications requiring maximum holding power. The magnet is specifically magnetized perpendicular to the 1/8-inch hole direction, making it suitable for specialized mounting, assembly, and positioning systems.
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 exceptional magnetic strength in a compact, symmetrical shape. Center-hole cube magnets are particularly useful for custom assemblies, alignment fixtures, automation equipment, and engineering applications that require mounting or integration into mechanical systems.
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 factors such as steel thickness, surface condition, air gaps, temperature, and application design. With a BrMax rating of 14,800 Gauss, it delivers maximum magnetic performance and is among the strongest commercially available neodymium magnets.
