Quick Answers

Question Answer
How strong is this magnet? Over 6.5 lbs pull force
Is N45 stronger than N42? Yes. N45 magnets provide greater magnetic energy and holding force than N42 magnets of the same size.
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, electronics, robotics, fixtures, magnetic assemblies, and DIY projects.

Product Overview

Rare earth neodymium magnets are the world's strongest permanent magnets available today. These N45 Neodymium Block Magnets measuring 3/8" x 3/8" x 1/8" deliver exceptional magnetic strength in a compact rectangular design. Their combination of high magnetic energy and convenient size makes them ideal for applications requiring powerful holding force in limited space.

Applied Magnets manufactures premium-quality NdFeB rare earth magnets using advanced production methods and strict quality control standards. Every magnet is engineered for consistent magnetic performance, superior durability, and long-term reliability across industrial, commercial, and hobby applications.

Featuring a Nickel-Copper-Nickel triple-layer protective coating, these N45 magnets offer excellent resistance to corrosion and wear. Their powerful magnetic field and compact footprint make them suitable for manufacturing, engineering, electronics, robotics, research, educational projects, and custom magnetic assemblies.

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 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 N45 neodymium block magnet produces approximately 6.5 pounds of pull force under ideal conditions when attached directly to a thick steel surface. The N45 grade provides higher magnetic performance than N42, N40, N38, and N35 magnets of the same dimensions. 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 over 6.5 lbs of pull force under ideal conditions on a thick, flat steel surface.

Is N45 stronger than N42?

Yes. N45 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 good corrosion resistance. However, prolonged exposure to moisture or harsh outdoor environments should be avoided.

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.
