Quick Answers

Question Answer
How strong is this magnet? Over 16 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, magnetic separators, fixtures, sensors, robotics, engineering projects, and industrial assemblies.

Product Overview

Neodymium magnets are the world's strongest permanent magnets, offering exceptional holding power and magnetic performance. These N45 Neodymium Bar Magnets measuring 2" x 1/2" x 1/8" are manufactured from premium NdFeB (Neodymium-Iron-Boron) material and provide outstanding strength in a slim rectangular profile.

Applied Magnets manufactures high-quality rare earth magnets using advanced production technology and stringent quality control standards. Every magnet is engineered for consistent magnetic performance, reliability, and long-term durability across industrial, commercial, and DIY applications.

Featuring a Nickel-Copper-Nickel triple-layer protective coating, these N45 bar magnets offer excellent resistance to corrosion while maintaining superior magnetic strength. Their elongated shape and strong magnetic field make them ideal for manufacturing, engineering, robotics, magnetic holding systems, scientific applications, and custom magnetic assemblies.

What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular or bar-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 bar magnet generates approximately 16 pounds of pull force under ideal conditions when attached directly to a thick steel surface. Its N45 grade provides stronger magnetic performance than N42, N40, N38, and N35 magnets of comparable size. Actual pull force may vary depending on surface conditions, steel thickness, air gaps, and application design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides over 16 lbs of pull force under ideal conditions on a thick, flat steel surface.

Is N45 stronger than N42?

Yes. N45 magnets deliver 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. However, prolonged exposure to moisture or harsh outdoor conditions should be avoided.

Can it rust?

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

What direction is it magnetized?

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