Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 9 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 magnets provide greater magnetic strength than N35, N38, and N40 magnets of the same size. |
| Can it be used outdoors? |
Yes. The Nickel-Copper-Nickel triple-layer coating provides excellent corrosion resistance. For continuous outdoor or marine exposure, additional sealing is recommended. |
| What is it commonly used for? |
Hidden magnetic mounts, deep magnetic closures, alignment systems, woodworking, electronics, fixtures, product assemblies, and DIY projects. |
Product Overview
The N42 Neodymium Cylinder Magnet 1/4" x 1" is engineered for applications that require extended magnetic reach and dependable holding power in a slim, space-saving design. Its 1/4-inch diameter fits easily into drilled holes and narrow installations, while the 1-inch length creates a deeper magnetic field and stronger engagement than shorter cylinder magnets, making it ideal for embedded mounting and precision assemblies.
Manufactured from premium N42 grade NdFeB (Neodymium-Iron-Boron), these rare earth magnets provide reliable magnetic performance across a wide range of industrial, commercial, and DIY applications. Their excellent balance of strength and control makes them ideal for woodworking, magnetic closures, electronics, fixtures, product design, and custom fabrication where compact size and consistent performance are important.
Each magnet is finished with a durable Nickel-Copper-Nickel triple-layer coating that helps resist corrosion, oxidation, and everyday wear while maintaining a smooth, polished appearance. Whether you're embedding magnets into wood, plastic, or resin or using them for positioning and alignment, these N42 cylinder magnets deliver long-lasting reliability.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a rod-shaped permanent magnet made from neodymium, iron, and boron (NdFeB). Its elongated shape creates a deeper magnetic field than a comparable disc magnet, making it an excellent choice for embedded installations, magnetic latches, positioning systems, alignment pins, and precision mechanical assemblies.
Cylinder magnets are widely used in manufacturing, woodworking, electronics, robotics, and engineering because they provide exceptional holding power while fitting into narrow drilled holes and compact spaces.
How Strong Is This Magnet?
This N42 cylinder magnet generates approximately 9 pounds of pull force under ideal conditions against a thick, flat steel surface. The extended 1-inch length produces a deeper magnetic field than shorter cylinders, providing stronger holding power and more secure engagement in embedded and alignment applications.
Because cylinder magnets have a relatively small contact surface, actual pull force may vary depending on the application, mating material, air gap, surface finish, and installation method. Testing in your specific application is recommended.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 9 pounds of pull force under ideal conditions against a thick steel surface.
Is N42 stronger than N35?
Yes. N42 provides significantly greater magnetic strength than N35 magnets of the same dimensions while offering an excellent balance of performance and value.
Can it rust?
Like all neodymium magnets, the core material can corrode if exposed. The Nickel-Copper-Nickel triple-layer coating provides excellent protection against moisture, oxidation, and everyday wear.
Can it be used outdoors?
Yes. For long-term outdoor or marine applications, an additional protective sealant is recommended to maximize service life.
What direction is it magnetized?
This cylinder magnet is axially magnetized through its length, meaning the north and south poles are located on the two circular ends.
