Quick Answers

Question Answer
How strong is this magnet? Approximately 19 lbs pull force
Is N52 stronger than N42? Yes. N52 is the strongest commercially available neodymium magnet grade and provides significantly more holding force than N42.
What is this magnet made of? NdFeB rare earth material
Can this magnet rust? The Nickel-Copper-Nickel coating provides excellent corrosion resistance, but damaged coatings may eventually allow oxidation.
What is it commonly used for? Manufacturing, engineering, magnetic assemblies, robotics, electronics, research, and heavy-duty holding applications.

Product Overview

Neodymium magnets are the world's strongest permanent magnets, and N52 magnets represent the highest standard commercial grade available. These 3/8" x 3/8" x 3/8" N52 neodymium cube magnets deliver exceptional magnetic strength in a compact cube design, making them ideal for demanding applications requiring maximum holding power.

Applied Magnets manufactures premium-quality NdFeB rare earth magnets using advanced production technology and strict quality control standards. Every magnet is engineered to provide consistent magnetic performance, long-term reliability, and superior durability.

Featuring a Nickel-Copper-Nickel triple-layer protective coating, these N52 cube magnets resist corrosion while maintaining outstanding magnetic performance. Their combination of compact size and powerful magnetic force makes them ideal for industrial, engineering, manufacturing, electronics, robotics, scientific, and custom magnetic assembly applications.

What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular or cube-shaped rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Block and cube magnets provide strong holding force and a large contact surface, making them ideal for industrial, engineering, manufacturing, and DIY applications.

How Strong Is This Magnet?

This N52 neodymium cube magnet produces approximately 19 pounds of pull force under ideal conditions when attached directly to a thick steel surface. With a Br Max of 14,800 gauss, it provides substantially more magnetic energy than lower grades such as N35, N38, N40, N42, N45, N48, and N50. Actual pull force may vary depending on mounting conditions, steel thickness, air gaps, and operating environment.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet generates approximately 19 lbs of pull force under ideal conditions on a thick, flat steel surface.

Is N52 stronger than N42?

Yes. N52 magnets provide significantly greater magnetic energy and holding force than N42 magnets of identical size.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides excellent corrosion resistance. However, prolonged exposure to moisture or harsh outdoor environments is not recommended.

Can it rust?

Neodymium magnets contain iron and may corrode if the protective coating becomes damaged.

What direction is it magnetized?

This magnet is magnetized through the thickness.
