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.

Do you offer bulk discounts?

Yes. Super Magnet Store offers wholesale pricing and quantity discounts for manufacturers, distributors, educational institutions, and OEM customers.

    Tiny but Mighty

    This 100-pack of small magnets has been a fantastic addition to my craft and DIY supplies. Don’t let their tiny size fool you, these magnets are impressively strong for how small they are. Each one is cleanly made and consistent in size, which is great when you're using multiple in a single project. They arrived well-packaged and undamaged, neatly stacked in a small box that keeps everything organized.I’ve already used these magnets for a variety of projects including miniatures, closure systems on small boxes, homemade fridge magnets, and even light-duty tool organization. They hold better than expected and are easy to work with when you have a steady hand and some patience due to their size. The strength is enough to hold lightweight items with no problem, and they’re perfect for projects that need something discreet and low-profile.This is excellent value for 100 strong, reliable little magnets. Whether you’re using them for crafts, modeling, organizing, or science experiments, these do the job. I appreciate that they’re consistent and high-quality, and having a bulk pack means I won’t run out any time soon. I highly recommend these if you’re looking for tiny, strong magnets that can be used in countless ways.

    Works well. The size was slightly too small for my purpose. Need to order next diameter.

    Nice little magnets.

    These are small, cylindrical rare-earth magnets. Pretty typical for the sort. Too small to hold much beyond a sheet of paper on the fridge, they have lots of uses for hobbyists. Drill matching holes in either side of a box and its lid and align the magnets carefully and they will do a good job of keeping the lid closed. They attract/repel each other end to end and make a fun toy to play with on a (non-metallic) surface.
