Product Overview

Neodymium block 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 reliable magnetic performance, exceptional strength, and long-lasting durability for commercial, industrial, and engineering applications.

This N42 neodymium block magnet measures 2" x 1/4" x 1/16" and generates approximately 5.5 lbs of pull force under ideal conditions. Manufactured from neodymium, iron, boron, and other minor elements, it delivers significantly greater magnetic performance than N40, N38, and N35 grades.

Its slim profile makes it ideal for applications requiring strong magnetic force in tight spaces. The Nickel-Copper-Nickel protective coating provides enhanced durability and corrosion resistance for long service life.

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 strong holding force and a large contact surface area while maintaining a compact profile, making them ideal for electronics, fixtures, displays, sensors, engineering projects, and custom magnetic assemblies.

How Strong Is This Magnet?

This N42 neodymium block magnet generates approximately 5.5 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 delivers dependable magnetic performance in a thin-profile design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides approximately 5.5 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, air gaps, steel thickness, and application design.

Is N42 stronger than N35?

Yes. N42 magnets provide substantially greater magnetic energy and holding force than N35 magnets of the same dimensions.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides 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 1/16-inch thickness, with the north and south poles located on the 2" x 1/4" large flat surfaces.
