Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 4 lbs or more of pull force under ideal conditions. |
| What is this magnet made of? |
NdFeB (Neodymium-Iron-Boron) rare earth material. |
| Is this stronger than N35 magnets? |
Yes. N52 is the highest standard neodymium grade and delivers substantially greater magnetic strength than N35, N38, N40, N42, and N48 magnets of the same size. |
| Can it be used outdoors? |
Yes. The Nickel-Copper-Nickel coating provides excellent corrosion resistance, although additional sealing is recommended for prolonged outdoor or marine environments. |
| What is it commonly used for? |
Magnetic closures, woodworking, electronics, embedded mounts, organization, crafts, displays, and DIY projects. |
Product Overview
The N52 Neodymium Disc Magnet 1/4" x 1/8" is engineered to provide maximum holding power in a compact, versatile size. Featuring a 1/4-inch diameter and a thicker 1/8-inch profile, this rare earth disc magnet produces a deeper magnetic field and stronger holding force than thinner disc magnets while maintaining a small footprint for easy installation.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these magnets deliver the highest magnetic strength available in standard neodymium grades. Their exceptional performance makes them ideal for woodworking, engineering, electronics, magnetic closures, product assembly, fixtures, and custom fabrication where dependable holding power is essential.
Each magnet is finished with a durable Nickel-Copper-Nickel triple-layer coating that provides excellent protection against corrosion while maintaining a smooth, polished appearance. Whether you're embedding magnets into wood, plastic, or resin, organizing tools, or designing precision assemblies, these N52 disc magnets offer outstanding strength, durability, and reliability.
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 recognized as the strongest commercially available permanent magnets, providing exceptional magnetic strength while remaining compact and lightweight.
Disc magnets are commonly used throughout manufacturing, electronics, robotics, woodworking, education, and consumer products because they provide excellent surface contact and can easily be concealed within assemblies, fixtures, and magnetic closures.
How Strong Is This Magnet?
This N52 neodymium disc magnet generates approximately 4 pounds or more of pull force under ideal conditions against a thick, flat steel surface. Its 1/8-inch thickness creates a deeper magnetic field than thinner disc magnets, providing increased holding power and greater stability for demanding applications.
The premium N52 magnetic grade delivers the highest magnetic energy available in standard neodymium magnets, making this an excellent choice whenever maximum performance is required in a compact disc magnet.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 4 pounds or more of pull force under ideal conditions against a thick steel surface.
Is N52 stronger than N35?
Yes. N52 is the strongest standard neodymium magnet grade and delivers substantially greater magnetic strength than N35 magnets of the same dimensions.
Can it rust?
Like all neodymium magnets, the core material can corrode if exposed. The Nickel-Copper-Nickel triple-layer coating provides excellent protection against moisture, oxidation, and everyday wear.
Can it be used outdoors?
Yes. For continuous outdoor or marine applications, an additional protective coating or sealant 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.
