Product Overview

Neodymium magnets are the world's strongest commercially available permanent magnets. Applied Magnets offers premium-quality N52 neodymium magnets manufactured to stringent quality standards using advanced production technology. These magnets provide exceptional magnetic strength, reliable performance, and outstanding value for industrial, commercial, and personal applications.

This N52 neodymium block magnet measures 3/4" x 1/2" x 1/4" and delivers approximately 20 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it provides significantly greater magnetic strength than N50, N48, N45, N42, N40, N38, and N35 grades.

The magnet features a durable Nickel-Copper-Nickel triple-layer coating that enhances corrosion resistance and surface durability. Manufactured under ISO-certified quality standards, these magnets provide consistent performance and long-term reliability 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 manufacturing, engineering, automation, robotics, electronics, and custom magnetic assemblies.

How Strong Is This Magnet?

This N52 neodymium block magnet generates approximately 20 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a BrMax rating of 14,800 Gauss, this magnet delivers maximum magnetic performance in a compact block design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides approximately 20 lbs of pull force under ideal conditions. Actual holding capacity depends on the surface material, steel thickness, and application design.

Is N52 stronger than N42?

Yes. N52 magnets provide significantly greater magnetic energy and holding power than N42 magnets of the same dimensions.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating offers excellent corrosion resistance, but additional protection is recommended for prolonged outdoor exposure.

Can it rust?

The protective nickel coating helps resist corrosion; however, moisture exposure and coating damage can eventually lead to 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 3/4" x 1/2" faces.
