Product Overview

Neodymium magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N42 neodymium block magnets manufactured to stringent quality standards using advanced production technology. These magnets provide dependable magnetic strength, consistent performance, and long-lasting durability for industrial, commercial, and engineering applications.

This N42 neodymium block magnet measures 3" x 1" x 1/4" and produces over 60 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers stronger magnetic performance than N40, N38, and N35 grades.

The Nickel-Copper-Nickel triple-layer coating provides excellent corrosion resistance and wear protection, making the magnet suitable for demanding industrial environments. Its large surface area and slim profile make it ideal for applications requiring strong holding force without excessive thickness.

What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular permanent magnet made from neodymium, iron, and boron (NdFeB). Block magnets provide powerful magnetic holding force across a broad surface area, making them ideal for industrial fixtures, magnetic lifting systems, manufacturing equipment, automation systems, and engineering projects.

How Strong Is This Magnet?

This N42 neodymium block magnet generates over 60 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 13,200 Gauss, it delivers reliable magnetic performance for industrial and commercial applications.

Frequently Asked Questions

How much weight can this magnet hold?

This magnet provides over 60 lbs of pull force under ideal conditions. Actual holding capacity depends on the steel surface, alignment, air gaps, and installation method.

Is N42 stronger than N35?

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

What direction is it magnetized?

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

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides excellent corrosion resistance. For prolonged outdoor or marine environments, additional sealing or a protective enclosure is recommended.

What is the maximum operating temperature?

This standard N42 magnet is designed for continuous operation up to 176°F (80°C). Exposure to higher temperatures may permanently reduce magnetic strength.

Do you offer wholesale pricing?

Yes. Contact Super Magnet Store for competitive wholesale pricing and volume discounts on N42 neodymium block magnets.

Safety Notice

Neodymium magnets are extremely powerful and can snap together unexpectedly, causing pinch injuries or chipping. Keep away from children, pacemakers, sensitive electronics, and magnetic storage devices. Always read and follow magnet safety guidelines before handling or installation.
