Quick Answers

Question Answer
How strong is this magnet? Approximately 1.6 lbs of pull force.
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 magnets of the same size.
Can it be used outdoors? Yes. The Nickel-Copper-Nickel coating provides corrosion resistance, although additional protection is recommended for long-term outdoor or marine exposure.
What is it commonly used for? Magnetic closures, woodworking, resin casting, electronics, alignment pins, crafts, hobby projects, organization, and precision assemblies.

Product Overview

The N42 Neodymium Cylinder Magnet 1/8" x 1/4" combines a slim profile with dependable holding power, making it an excellent solution for projects that require strength in confined spaces. Its narrow 1/8-inch diameter fits easily into drilled holes and compact assemblies, while the 1/4-inch length provides increased magnetic reach and improved holding performance compared to shorter cylinder magnets.

Manufactured from premium N42 grade NdFeB (Neodymium-Iron-Boron), these rare earth magnets deliver reliable magnetic performance for light to moderate-duty applications. The durable Nickel-Copper-Nickel triple-layer coating helps resist corrosion while providing a smooth, professional finish that withstands repeated handling.

Supplied in a convenient 100-piece pack, these cylinder magnets are ideal for manufacturers, woodworkers, hobbyists, engineers, and DIY enthusiasts who need a dependable supply of precision magnets for ongoing projects.

What Is a Neodymium Cylinder Magnet?

A neodymium cylinder magnet is a round rod-shaped permanent magnet made from neodymium, iron, and boron (NdFeB). Cylinder magnets provide a greater magnetic field depth than thinner disc magnets, making them ideal for embedded installations, alignment applications, and precision assemblies.

Their compact shape allows them to be easily installed into drilled holes, plastic housings, wooden projects, and custom components while delivering strong magnetic performance in a minimal footprint.

How Strong Is This Magnet?

Although measuring only 1/8 inch in diameter, this N42 cylinder magnet delivers approximately 1.6 pounds of pull force under ideal conditions against a thick steel surface. Its extended 1/4-inch length increases magnetic field depth, providing a stronger and more secure hold than shorter magnets of the same diameter.

Common Questions About This Magnet

What is the pull force?

This magnet provides approximately 1.6 pounds of pull force under ideal conditions.

Is N42 stronger than N35?

Yes. N42 magnets deliver noticeably greater magnetic strength than N35 magnets of identical dimensions.

Can it rust?

Like all neodymium magnets, the core material can corrode if exposed. The Nickel-Copper-Nickel coating provides excellent protection against everyday moisture and wear.

Can it be used outdoors?

Yes, although additional sealing is recommended for prolonged outdoor or marine environments.

What direction is it magnetized?

This cylinder magnet is magnetized through its length, with the north and south poles located on the two circular ends.
