What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Block magnets provide exceptional magnetic strength and a large contact surface area, making them ideal for industrial automation, manufacturing, engineering projects, robotics, electronics, and custom magnetic assemblies.

How Strong Is This Magnet?

This N52 neodymium block magnet generates over 26 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, operating temperature, and mounting configuration. With a Br Max rating of 14,800 Gauss, it provides industry-leading magnetic performance in a compact footprint.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides over 26 lbs of pull force under ideal conditions. Actual holding strength depends on the steel surface, air gap, and application design.

Is N52 stronger than N42?

Yes. N52 magnets provide significantly greater magnetic energy and holding force than N42 magnets of the same dimensions.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating offers excellent corrosion resistance. For extended outdoor use or exposure to moisture, additional protective sealing is recommended.

Will this magnet lose strength over time?

Neodymium magnets retain their magnetism indefinitely under normal conditions. Exposure to temperatures above 176°F (80°C) may permanently reduce magnetic strength.

What direction is it magnetized?

This magnet is magnetized through the 1/4-inch thickness, with the north and south poles located on the 1" x 1/2" surfaces.
