Quick Answers

Question Answer
How strong is this magnet? Over 26 lbs of pull force under ideal conditions.
Is N42 stronger than N35? Yes. N42 provides 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 resist corrosion, but prolonged exposure to moisture or coating damage may eventually lead to corrosion.
What is it commonly used for? Industrial fixtures, magnetic assemblies, engineering projects, manufacturing equipment, robotics, and heavy-duty holding applications.

Product Overview

Rare earth neodymium magnets are the world's strongest commercially available permanent magnets. Applied Magnets offers premium-quality N42 neodymium magnets manufactured using advanced production technology and stringent quality standards. These magnets provide dependable performance, strong holding power, and excellent value for industrial, engineering, and commercial applications.

This N42 neodymium block magnet measures 3/4" x 3/4" x 1/4" and generates over 26 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers superior magnetic performance compared to N35, N38, and N40 grades.

The magnet features a durable Nickel-Copper-Nickel triple-layer coating for enhanced corrosion resistance and long service life. Manufactured under ISO-certified quality standards, these magnets provide consistent magnetic strength and reliable performance in demanding environments.

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 offer exceptional magnetic strength and a large contact surface area, making them ideal for industrial equipment, manufacturing fixtures, robotics, engineering projects, and custom magnetic assemblies.

How Strong Is This Magnet?

This N42 neodymium block magnet produces over 26 lbs of pull force under ideal conditions. Actual holding strength depends on factors such as steel thickness, surface condition, air gaps, temperature, and mounting configuration. With a BrMax rating of 13,200 Gauss, it provides powerful magnetic performance in a compact block design.

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 capacity depends on the steel surface, mounting configuration, 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 dimensions.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides good corrosion resistance, but additional protection is recommended for long-term outdoor use.

Can it rust?

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

What direction is it magnetized?

This magnet is magnetized through the 1/4-inch thickness, with the north and south poles located on the two 3/4" x 3/4" faces.
