Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 6.5 lbs 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 provides 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 triple-layer coating provides excellent corrosion resistance. For continuous outdoor or marine environments, additional sealing is recommended. |
| What is it commonly used for? |
Precision alignment, magnetic closures, embedded mounting, woodworking, electronics, fixtures, organization, and DIY projects. |
Product Overview
The N52 Neodymium Cylinder Magnet 1/4" x 1/4" delivers maximum magnetic performance in a compact, perfectly balanced cylindrical design. Measuring 1/4 inch in diameter and 1/4 inch in length, this premium rare earth magnet fits neatly into drilled holes, molded components, and precision assemblies while providing exceptional holding power and accurate alignment.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these cylinder magnets provide the highest magnetic strength available in standard neodymium magnets. Their superior performance makes them an excellent choice for woodworking, engineering, robotics, electronics, product assembly, magnetic closures, and custom fabrication where compact size and maximum holding force are equally important.
Each magnet features a durable Nickel-Copper-Nickel triple-layer coating that offers outstanding resistance to corrosion, oxidation, and everyday wear while maintaining a smooth, polished appearance. Compared to standard epoxy-coated magnets, the triple-layer nickel finish provides significantly greater durability, helping preserve both the appearance and long-term performance of the magnet.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a rod-shaped permanent magnet manufactured from neodymium, iron, and boron (NdFeB). Its cylindrical shape creates a deeper magnetic field than a similarly sized disc magnet, making it ideal for embedded installations, positioning systems, magnetic latches, alignment pins, and precision mechanical assemblies.
Their equal diameter and height provide excellent stability while allowing easy installation into drilled holes, plastic housings, wood, resin, and custom-machined components.
How Strong Is This Magnet?
This N52 cylinder magnet generates approximately 6.5 pounds of pull force under ideal conditions against a thick, flat steel surface. Its balanced 1/4-inch diameter and 1/4-inch length create an excellent combination of holding strength, magnetic field depth, and installation flexibility.
The premium N52 magnetic grade delivers the highest magnetic energy available in standard neodymium magnets, making this an ideal solution for demanding applications where maximum strength is required in a compact footprint.
Because cylinder magnets have a relatively small contact surface, actual pull force may vary depending on the application, material thickness, air gap, surface finish, and mounting method. Testing in your specific application is recommended.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 6.5 pounds of pull force under ideal conditions. Actual holding force may vary depending on the application and contact 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 superior corrosion resistance and is considerably more durable than standard epoxy-coated magnets.
Can it be used outdoors?
Yes. For long-term outdoor or marine applications, an additional protective sealant is recommended to maximize service life.
What direction is it magnetized?
This cylinder magnet is axially magnetized through its length, meaning the north and south poles are located on the two circular ends.
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.
