Product Overview
The N48 Neodymium Disc Magnet 1/4" x 1/8" is designed to provide exceptional holding power in a compact and versatile size. Featuring a 1/4-inch diameter and a thicker 1/8-inch profile, this rare earth disc magnet delivers a stronger magnetic field and improved holding performance than thinner magnets while maintaining a small installation footprint.
Manufactured from premium N48 grade NdFeB (Neodymium-Iron-Boron), these magnets provide enhanced magnetic strength over standard grades, making them an excellent choice for woodworking, magnetic closures, electronics, product assembly, displays, and countless DIY projects. The added thickness increases stability and holding power, making these magnets especially effective on flat steel surfaces.
Each magnet is finished with a durable Nickel-Copper-Nickel triple-layer coating that helps protect against corrosion while providing a smooth, polished appearance. Whether you're building custom products, organizing hardware, or embedding magnets into wood, plastic, or resin, these N48 disc magnets offer dependable performance and long service life.
What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a circular permanent magnet manufactured from neodymium, iron, and boron (NdFeB). These rare earth magnets are the strongest commercially available permanent magnets and are widely used in engineering, manufacturing, electronics, woodworking, education, and consumer products.
Disc magnets are popular because they provide excellent surface contact and can easily be embedded into flat materials while delivering exceptional magnetic performance in a compact package.
How Strong Is This Magnet?
This N48 neodymium disc magnet produces approximately 3.6 pounds or more of pull force under ideal conditions against a thick, flat steel surface. Its 1/8-inch thickness generates a deeper magnetic field than thinner disc magnets, resulting in stronger holding power and greater reliability across a wide variety of applications.
With its premium N48 magnetic grade, this magnet offers enhanced magnetic performance compared to N42 and lower-grade neodymium magnets, making it an excellent balance of strength, size, and value.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 3.6 pounds or more of pull force under ideal conditions against a thick steel surface.
Is N48 stronger than N35?
Yes. N48 magnets generate significantly greater magnetic strength than N35 magnets of identical dimensions, making them an excellent choice when increased holding power is required.
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, oxidation, and everyday wear.
Can it be used outdoors?
Yes. For long-term outdoor or marine applications, additional sealing is recommended to maximize service life.
What direction is it magnetized?
This magnet is magnetized through its thickness, meaning the north and south poles are located on the two flat circular faces.
Do you offer bulk discounts?
Yes. Super Magnet Store offers competitive wholesale pricing and quantity discounts for manufacturers, distributors, educational institutions, retailers, and OEM customers.
