Product Overview
The N48 Neodymium Cylinder Magnet 1/8" x 1/2" is designed for applications requiring maximum magnetic reach in a slim, compact profile. Measuring just 1/8 inch in diameter with an extended 1/2-inch length, this rare earth cylinder magnet generates a deeper magnetic field than shorter magnets, making it ideal for projects where stronger holding power is needed without increasing the magnet's diameter.
Manufactured from premium N48 grade NdFeB (Neodymium-Iron-Boron), these magnets provide higher magnetic performance than standard grades, making them an excellent choice for woodworking, electronics, engineering, and custom fabrication. Their slender design allows for easy installation in narrow drilled holes, plastic housings, resin castings, and other confined spaces where precision matters.
Each magnet is protected by a durable Nickel-Copper-Nickel triple-layer coating that helps resist corrosion while providing a smooth, polished finish. Supplied in a convenient 100-piece pack, these magnets are ideal for manufacturers, woodworkers, engineers, hobbyists, and DIY enthusiasts who require dependable, high-strength magnets for repeated use.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a rod-shaped permanent magnet manufactured from neodymium, iron, and boron (NdFeB). Its elongated shape creates a deeper magnetic field than a comparable disc magnet, making cylinder magnets especially useful for embedded installations, alignment pins, magnetic latches, sensors, and precision mechanical assemblies.
Their narrow profile allows them to fit into drilled holes, molded components, wooden projects, and compact mechanical systems while delivering exceptional magnetic performance.
How Strong Is This Magnet?
Despite its slim 1/8-inch diameter, this N48 cylinder magnet produces approximately 2.9 pounds of pull force under ideal conditions against a thick steel surface. Its 1/2-inch length increases magnetic field depth, allowing for improved holding strength and a more secure magnetic connection than shorter cylinder magnets.
The premium N48 grade provides enhanced magnetic energy over standard neodymium grades, making it an excellent solution for demanding precision applications.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 2.9 pounds of pull force when used against a thick, flat steel surface under ideal conditions.
Is N48 stronger than N35?
Yes. N48 magnets generate significantly greater magnetic strength than N35 magnets of identical dimensions, making them ideal for applications requiring greater holding power.
Can it rust?
Like all neodymium magnets, the core material can corrode if left unprotected. The Nickel-Copper-Nickel triple-layer coating provides excellent resistance to moisture and everyday wear.
Can it be used outdoors?
Yes. For prolonged outdoor exposure or marine environments, an additional protective coating or sealant is recommended to maximize durability.
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.
