Product Overview
The N42 Neodymium Cylinder Magnet 3/16" x 3/16" is designed for balanced performance and precision in a compact, symmetrical shape. With both its diameter and length measuring 3/16 inch, this cylinder magnet is ideal for applications that require accurate alignment, secure positioning, and consistent magnetic performance. Its equal dimensions make it especially easy to install into drilled holes and precision assemblies.
Manufactured from premium N42 grade NdFeB (Neodymium-Iron-Boron), these rare earth magnets provide dependable holding power for a wide variety of industrial, commercial, and hobby applications. Their compact size makes them perfect for woodworking, product assembly, electronics, magnetic closures, resin casting, and custom fabrication where space is limited but reliable performance is essential.
Each magnet is protected by a durable Nickel-Copper-Nickel triple-layer coating that helps resist corrosion while providing a smooth, polished finish. Whether you're building custom projects, organizing small components, or creating precision fixtures, these N42 cylinder magnets deliver consistent strength and long-lasting durability.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a rod-shaped permanent magnet manufactured from neodymium, iron, and boron (NdFeB). Its cylindrical design provides a deeper magnetic field than a comparable disc magnet, making it ideal for alignment pins, embedded mounting, positioning systems, magnetic latches, and precision mechanical assemblies.
Because of their balanced dimensions and strong magnetic performance, cylinder magnets are commonly used in manufacturing, woodworking, electronics, robotics, and engineering applications.
How Strong Is This Magnet?
This N42 cylinder magnet produces approximately 2.2 pounds of pull force under ideal conditions against a thick, flat steel surface. Its balanced 3/16-inch diameter and length provide an excellent combination of magnetic strength, stability, and ease of installation.
Because cylinder magnets have a relatively small contact surface, actual pull force may vary depending on the application, mating material, air gap, and mounting method. Testing in your specific application is recommended.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 2.2 pounds of pull force under ideal conditions. Actual holding force may vary depending on the application and contact surface.
Is N42 stronger than N35?
Yes. N42 provides noticeably greater magnetic strength than N35 magnets of the same dimensions while maintaining excellent value and versatility.
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 corrosion and everyday wear.
Can it be used outdoors?
Yes. For continuous outdoor or marine environments, additional sealing 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.
