Product Overview

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

This N42 neodymium plate magnet measures 6" x 1/8" x 5/16" and produces approximately 28 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other rare earth elements, it delivers stronger magnetic performance than N40, N38, and N35 grades.

Its Nickel-Copper-Nickel triple-layer coating provides excellent corrosion resistance and surface durability, while the long, narrow profile makes it ideal for applications requiring extended magnetic coverage in a compact design.

What Is a Neodymium Plate Magnet?

A neodymium plate magnet is a long, flat permanent magnet made from neodymium, iron, and boron (NdFeB). Plate magnets provide powerful magnetic force across an extended surface area, making them ideal for magnetic holding systems, fixtures, automation equipment, sensors, cabinetry, manufacturing, and engineering applications.

How Strong Is This Magnet?

This N42 neodymium plate magnet generates approximately 28 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 provides dependable magnetic performance for industrial and commercial use.

Frequently Asked Questions

How much weight can this magnet hold?

This magnet provides approximately 28 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 similar size.

What direction is it magnetized?

The magnet is magnetized through the 5/16-inch thickness, with the north and south poles located on the 6" × 1/8" faces.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating offers excellent corrosion resistance. For prolonged outdoor, marine, or high-humidity 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). Temperatures above this limit 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 plate magnets.

Safety Notice

Neodymium magnets are extremely powerful and can snap together unexpectedly, causing pinch injuries or chipping. Handle with care and keep away from children, pacemakers, sensitive electronics, magnetic storage devices, and loose ferrous objects. Always review magnet safety guidelines before handling or installation.
