Product Overview

Neodymium magnets are the world's strongest commercially available permanent magnets. Applied Magnets offers premium-quality N48 neodymium magnets manufactured to stringent quality standards using advanced production technology. These magnets deliver outstanding magnetic performance, reliable strength, and exceptional value for industrial and commercial applications.

This N48 neodymium block magnet measures 3/4" x 1/2" x 1/4" and generates approximately 19 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it provides stronger magnetic performance than N45, N42, N40, N38, and N35 grades.

The magnet is protected by a durable Nickel-Copper-Nickel triple-layer coating that enhances corrosion resistance and long-term durability. Manufactured under ISO-certified quality standards, these magnets provide consistent magnetic performance and superior 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 provide exceptional holding force and a large contact surface area, making them ideal for manufacturing, engineering, robotics, automation, electronics, and custom magnetic assemblies.

How Strong Is This Magnet?

This N48 neodymium block magnet generates approximately 19 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting conditions. With a BrMax rating of 14,200 Gauss, this magnet delivers powerful magnetic performance in a compact block design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides approximately 19 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, steel thickness, and application design.

Is N48 stronger than N42?

Yes. N48 magnets provide greater magnetic energy and holding force 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.
