Quick Answers

Question Answer
How strong is this magnet? Approximately 25 lbs of pull force under ideal conditions.
What is this magnet made of? NdFeB (Neodymium-Iron-Boron) rare earth material.
Is this stronger than N35 magnets? Yes. N42 provides significantly greater magnetic strength than N35, N38, and N40 magnets of the same size.
Can it be used outdoors? Yes, but additional sealing is recommended for long-term exposure to moisture or harsh environments.
What is it commonly used for? Embedded mounting, magnetic fixtures, woodworking, industrial assemblies, sensors, and DIY projects.

Product Overview

These 3/8" x 3/4" N42 Neodymium Cylinder Magnets are engineered for applications requiring extended magnetic reach and dependable holding power in a slim, compact profile. The 3/8-inch diameter provides solid surface contact, while the longer 3/4-inch height creates a deeper magnetic field and greater stability than shorter cylinder magnets, making them ideal for embedded installations and precision assemblies.

Manufactured from premium N42 grade rare earth neodymium, these magnets deliver an excellent balance of strength, reliability, and ease of handling. They're well suited for woodworking, fixtures, magnetic closures, industrial equipment, sensors, and custom fabrication where consistent performance is essential.

Each magnet is protected by a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, offering excellent resistance to corrosion, scratches, and chipping while maintaining a smooth, polished metallic finish.

What Is a Neodymium Cylinder Magnet?

A neodymium cylinder magnet is a permanent magnet made from NdFeB (Neodymium-Iron-Boron), the strongest commercially available magnetic material. Its elongated cylindrical shape produces a deeper magnetic field than shorter magnets of the same diameter, making it an excellent choice for applications requiring increased holding depth and precise positioning.

These magnets are magnetized through their thickness (height), placing the north and south poles on the two flat circular ends for maximum magnetic performance.

How Strong Is This Magnet?

This 3/8" x 3/4" N42 cylinder magnet delivers approximately 25 pounds of pull force under ideal testing conditions using a thick, clean steel surface.

Because cylinder magnets have a relatively small contact area, actual pull force can vary depending on the thickness, flatness, finish, and material of the mating surface. We recommend testing the magnet in your specific application to verify performance.

Common Questions About This Magnet

What is the pull force?

This magnet delivers approximately 25 pounds of pull force under ideal conditions. Actual pull force may vary depending on the application and contact surface.

Is N42 stronger than N35?

Yes. N42 provides significantly greater magnetic strength and energy than N35 magnets of the same dimensions.

Can it rust?

Like all neodymium magnets, it contains iron and may corrode if the protective coating is damaged or if exposed to moisture for extended periods.

Can it be used outdoors?

Yes. However, additional sealing is recommended for long-term outdoor or marine environments.

What direction is it magnetized?

This magnet is magnetized through its thickness (height), with the north and south poles located on the two flat circular ends.
