Product Overview

Neodymium block magnets are the world's strongest commercially available permanent magnets. Super Magnet Store offers premium-quality N48 neodymium block magnets manufactured to stringent quality standards using advanced production technology. These magnets provide exceptional magnetic strength, dependable performance, and long-term durability for industrial, commercial, and engineering applications.

This N48 neodymium block magnet measures 2" x 1" x 3/8" and generates over 65 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers stronger magnetic performance than N45, N42, N40, N38, and N35 grades.

The Nickel-Copper-Nickel triple-layer coating provides superior protection against corrosion and wear while maintaining long-term magnetic performance. Manufactured under ISO-certified quality standards, this magnet offers consistent strength and reliability for demanding industrial applications.

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 industrial equipment, manufacturing fixtures, automation systems, robotics, engineering projects, and custom magnetic assemblies.

How Strong Is This Magnet?

This N48 neodymium block magnet generates over 65 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a Br Max rating of 14,200 Gauss, it delivers powerful magnetic performance in a compact industrial-grade design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides over 65 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, air gaps, 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 provides 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 result in rust.

What direction is it magnetized?

This magnet is magnetized through the 3/8-inch thickness, with the north and south poles located on the 2" x 1" flat surfaces.
