Product Overview

Neodymium magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N52 neodymium bar magnets manufactured to stringent quality standards using advanced production technology. These magnets deliver exceptional magnetic strength, reliable performance, and long-term durability for industrial, commercial, and engineering applications.

This N52 neodymium bar magnet measures 3" x 1/2" x 1/8" and generates approximately 24 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other rare earth elements, it provides stronger magnetic performance than N50, N48, N45, N42, N40, N38, and N35 grades.

The magnet features a durable Nickel-Copper-Nickel triple-layer coating that provides excellent resistance to corrosion and everyday wear. Manufactured under ISO-certified quality standards and NdFeB patent licensing, it delivers consistent, dependable magnetic performance for demanding applications.

What Is a Neodymium Bar Magnet?

A neodymium bar magnet is a rectangular rare earth permanent magnet manufactured from neodymium, iron, and boron (NdFeB). Its elongated profile provides a large magnetic contact area while maintaining a slim footprint, making it ideal for industrial fixtures, magnetic assemblies, automation systems, robotics, sensors, and custom engineering projects.

How Strong Is This Magnet?

This N52 neodymium bar magnet generates approximately 24 lbs of pull force under ideal conditions. Actual holding force depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a Br Max rating of 14,500 Gauss, it provides outstanding magnetic performance in a compact design.

Frequently Asked Questions

How much weight can this magnet hold?

This magnet provides approximately 24 lbs of pull force under ideal conditions. Actual holding capacity depends on the steel surface, alignment, air gaps, and installation method.

Is N52 stronger than N50?

Yes. N52 provides the highest magnetic energy of standard commercial neodymium magnets and offers greater holding force than N50 magnets of the same size.

What direction is it magnetized?

The magnet is magnetized through the 1/8-inch thickness, with the north and south poles located on the 3" × 1/2" faces.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating offers excellent corrosion resistance. For continuous outdoor or marine exposure, we recommend sealing the magnet or installing it in a protective housing.

What is the maximum operating temperature?

This standard N52 magnet is designed for continuous operation up to 176°F (80°C). Higher temperatures may cause permanent loss of magnetic strength.

Do you offer wholesale pricing?

Yes. Contact Super Magnet Store for competitive wholesale pricing and volume discounts on N52 neodymium bar 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 review magnet safety guidelines before handling or installation.
