Product Overview
The N48 Neodymium Disc Magnet 1/8" x 1/16" is an excellent choice when you need maximum magnetic performance in a compact package. Measuring just 1/8 inch in diameter and 1/16 inch thick, this powerful rare earth magnet delivers impressive holding strength while fitting into tight spaces where larger magnets cannot.
Manufactured from premium N48 grade NdFeB (Neodymium-Iron-Boron) material, this disc magnet provides stronger magnetic performance than lower-grade magnets of the same size, making it ideal for precision applications, electronics, crafts, and light-duty holding projects. Its Nickel-Copper-Nickel triple-layer coating offers excellent corrosion resistance and a smooth, professional finish for long-lasting durability.
Whether you're building miniature models, embedding magnets into wood or resin, designing custom products, or organizing small tools and components, this compact N48 disc magnet delivers dependable performance and exceptional value.
What Is a Neodymium Disc Magnet?
A neodymium disc magnet is a round permanent magnet manufactured from an alloy of neodymium, iron, and boron (NdFeB). These rare earth magnets are the strongest commercially available permanent magnets, providing exceptional magnetic strength relative to their size.
Their compact shape makes disc magnets ideal for electronics, sensors, robotics, magnetic closures, fixtures, hobby projects, and industrial applications where space is limited but reliable magnetic performance is required.
How Strong Is This Magnet?
Despite its small 1/8-inch diameter, this N48 neodymium disc magnet generates approximately 0.9 pounds of pull force under ideal conditions against a thick, flat steel surface.
Its higher magnetic energy compared to N35 and N42 grades allows engineers, hobbyists, and manufacturers to achieve stronger holding power without increasing the size of their designs.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 0.9 pounds of pull force under ideal conditions.
Is N48 stronger than N35?
Yes. N48 magnets produce significantly more magnetic strength than N35 magnets of identical dimensions, making them an excellent choice for compact, high-performance applications.
Can it rust?
Like all neodymium magnets, the core material can corrode if exposed. The Nickel-Copper-Nickel triple coating helps protect the magnet from moisture and everyday wear.
Can it be used outdoors?
Yes, for many applications. However, for continuous outdoor or marine environments, additional protective sealing is recommended to maximize service life.
What direction is it magnetized?
This magnet is magnetized through its thickness, with the north and south poles located on the two flat circular faces.
Do you offer bulk discounts?
Yes. Super Magnet Store offers competitive quantity pricing and wholesale discounts for manufacturers, distributors, schools, and OEM customers.
