Quick Answers

Question Answer
How strong is this magnet? More than 27 lbs of pull force under ideal conditions.
Is N42 stronger than N35? Yes. N42 magnets provide significantly greater magnetic strength than N35, N38, and N40 grades.
What is this magnet made of? NdFeB (Neodymium-Iron-Boron) rare earth material.
Can this magnet rust? The Nickel-Copper-Nickel coating helps protect against corrosion, but prolonged exposure to moisture or coating damage can eventually lead to rust.
What is it commonly used for? Industrial fixtures, manufacturing, robotics, magnetic assemblies, engineering projects, research, electronics, and DIY applications.

Product Overview

Neodymium cube magnets are among the world's strongest commercially available permanent magnets. Applied Magnets offers premium-quality neodymium cube magnets manufactured to stringent quality standards using advanced production technology. These magnets provide exceptional magnetic strength, consistent performance, and outstanding value for industrial, commercial, educational, and hobby applications.

This N42 neodymium cube magnet measures 1/2" x 1/2" x 1/2" and generates more than 27 pounds of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers substantially greater magnetic strength than lower grades such as N35, N38, and N40.

The magnet features a durable Nickel-Copper-Nickel triple-layer coating that provides excellent corrosion resistance and long-term durability. Manufactured under ISO-certified standards, these magnets deliver dependable magnetic performance and superior quality for demanding applications.

What Is a Neodymium Block Magnet?

A neodymium block or cube magnet is a rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Cube magnets provide exceptional holding force in a symmetrical shape, making them ideal for industrial equipment, engineering projects, robotics, manufacturing fixtures, electronics, and custom magnetic assemblies.

How Strong Is This Magnet?

This N42 neodymium cube magnet produces more than 27 pounds of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface condition, air gaps, temperature, and mounting configuration. With a BrMax rating of 13,200 Gauss, this magnet delivers impressive magnetic performance in a compact cube design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet generates more than 27 lbs of pull force under ideal conditions. Actual holding capacity depends on the mounting surface, air gap, and application design.

Is N42 stronger than N35?

Yes. N42 magnets provide substantially greater magnetic energy and holding force than N35 magnets of the same size.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating offers corrosion resistance, but additional protection is recommended for prolonged outdoor exposure.

Can it rust?

The protective nickel coating helps resist corrosion; however, moisture exposure and coating damage can eventually cause rust.

What direction is it magnetized?

This magnet is magnetized through the thickness, with the north and south poles located on opposite faces of the cube.
