Quick Answers

Question Answer
How strong is this magnet? Approximately 15 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? Precision alignment, embedded mounting, magnetic closures, woodworking, shop organization, and DIY projects.

Product Overview

These 3/8" x 3/8" N42 Neodymium Cylinder Magnets combine a balanced cylindrical design with dependable magnetic strength for a wide variety of applications. With equal diameter and height, they fit neatly into drilled holes and precision-machined components, making them an excellent choice for projects that require accurate positioning, repeatable alignment, and reliable holding power.

Manufactured from premium N42 grade rare earth neodymium, these magnets provide an excellent balance of strength and control. They are ideal for woodworking, magnetic closures, fixtures, embedded mounting, custom fabrication, and light to moderate-duty industrial applications 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 manufactured from NdFeB (Neodymium-Iron-Boron), the world's strongest commercially available magnetic material. Cylinder magnets are ideal for applications requiring deeper magnetic fields than flat disc magnets while maintaining a compact footprint.

These magnets are magnetized through their height (thickness), placing the north and south poles on the two flat circular ends. Their shape makes them well suited for alignment, positioning, embedded installations, fixtures, sensors, and magnetic holding applications.

How Strong Is This Magnet?

This 3/8" x 3/8" N42 cylinder magnet provides approximately 15 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 may vary depending on the thickness, flatness, finish, and material of the mating surface. Testing in your intended application is recommended for the most accurate results.

Common Questions About This Magnet

What is the pull force?

This magnet delivers approximately 15 pounds of pull force under ideal conditions. Actual pull force depends 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 can corrode if the protective coating becomes damaged or if exposed to moisture for extended periods.

Can it be used outdoors?

Yes. However, for long-term outdoor or marine applications, additional sealing is recommended to maximize corrosion resistance.

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.
