Product Overview

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

This N42 neodymium block magnet measures 2" x 2" x 1/4" and generates approximately 52 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers stronger magnetic performance than N40, N38, and N35 grades.

The Nickel-Copper-Nickel triple-layer coating provides outstanding protection against corrosion and wear while maintaining long-term magnetic performance. Its large 2-inch square face provides excellent surface contact for secure holding and mounting 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, automation systems, manufacturing fixtures, engineering projects, magnetic assemblies, and custom applications.

How Strong Is This Magnet?

This N42 neodymium block magnet generates approximately 52 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 13,200 Gauss, it provides reliable magnetic performance for demanding applications.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides approximately 52 lbs of pull force under ideal conditions. Actual holding capacity depends on steel thickness, surface material, air gaps, and application design.

Is N42 stronger than N35?

Yes. N42 provides significantly greater magnetic strength and holding force than N35 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 or high-humidity environments.

Can it rust?

The protective nickel coating helps resist corrosion; however, damage to the coating or prolonged moisture exposure may eventually allow corrosion to develop.

What direction is it magnetized?

This magnet is magnetized through the 1/4-inch thickness, with the north and south poles located on the 2" x 2" flat surfaces.
