Product Overview

Rare earth neodymium magnets are the world's strongest permanent magnets. Manufactured from premium NdFeB (Neodymium-Iron-Boron), these N42 block magnets deliver exceptional magnetic performance in a compact size. Measuring 1/4" x 1/4" x 1/16", they provide impressive holding force while fitting into applications where space is limited.

Applied Magnets manufactures high-quality rare earth magnets using premium neodymium, iron, and boron raw materials. Every magnet is produced under strict quality standards to ensure consistent magnetic strength, durability, and reliability. These magnets feature a Nickel-Copper-Nickel triple-layer coating for maximum protection against corrosion and wear.

Neodymium magnets are the strongest type of permanent magnet available and offer the highest energy product among commercially available permanent magnets. Their compact size and powerful magnetic field make them ideal for industrial, engineering, manufacturing, electronics, educational, and hobby applications.

What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular or cube-shaped rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Block magnets provide strong holding force and a large contact surface, making them ideal for industrial, engineering, manufacturing, and DIY applications.

How Strong Is This Magnet?

This N42 neodymium block magnet generates approximately 2.7 pounds of pull force under ideal conditions when attached directly to a thick steel surface. Actual performance may vary depending on the application, surface material, air gap, and operating environment. Pull force values should be considered estimates and tested in your specific application.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides approximately 2.7 lbs of pull force under ideal conditions on a thick, flat steel surface.

Is N42 stronger than N35?

Yes. N42 magnets deliver noticeably greater magnetic energy and holding force than N35 magnets of the same dimensions.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating offers good corrosion resistance. However, long-term exposure to moisture or harsh environments may eventually degrade the coating.

Can it rust?

Yes. Neodymium magnets contain iron and can corrode if the protective coating becomes damaged.

What direction is it magnetized?

This magnet is magnetized through the thickness.

Do you offer wholesale pricing?

Yes. Contact Applied Magnets for volume pricing and wholesale discounts.
