Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 8 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, although additional sealing is recommended for prolonged outdoor or marine environments. |
| What is it commonly used for? |
Hidden magnetic mounts, precision alignment, magnetic closures, woodworking, electronics, product assemblies, fixtures, and DIY projects. |
Product Overview
The N52 Neodymium Cylinder Magnet 1/4" x 3/8" is engineered to deliver exceptional magnetic performance in a compact, elongated design. Featuring a 1/4-inch diameter and an extended 3/8-inch length, this premium rare earth magnet generates a deeper magnetic field and stronger holding power than shorter cylinder magnets while remaining easy to install in confined spaces.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these cylinder magnets provide the highest magnetic strength available in standard neodymium magnets. Their combination of compact size and powerful holding force makes them ideal for woodworking, engineering, robotics, electronics, magnetic closures, fixtures, product assemblies, and countless precision applications.
Each magnet features a durable Nickel-Copper-Nickel triple-layer coating that provides outstanding protection against corrosion, oxidation, and everyday wear while maintaining a smooth, polished finish. Whether you're embedding magnets into wood, plastic, or resin or using them for alignment and positioning, these N52 cylinder magnets deliver dependable, long-lasting performance.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a rod-shaped permanent magnet manufactured from neodymium, iron, and boron (NdFeB). The elongated cylindrical design creates a deeper magnetic field than a comparable disc magnet, making cylinder magnets ideal for embedded mounting, magnetic latches, positioning systems, alignment pins, and precision mechanical assemblies.
Their compact diameter allows them to fit neatly into drilled holes and molded components while providing exceptional magnetic strength in applications where installation space is limited.
How Strong Is This Magnet?
This N52 cylinder magnet produces approximately 8 pounds of pull force under ideal conditions against a thick, flat steel surface. Its 3/8-inch length increases magnetic field depth compared to shorter cylinders, providing stronger engagement and a more secure hold.
The premium N52 magnetic grade offers the highest magnetic energy available in standard neodymium magnets, making this cylinder magnet an excellent choice for demanding applications requiring maximum strength in a compact size.
Because cylinder magnets have a relatively small contact surface, actual pull force may vary depending on the application, material thickness, surface finish, air gap, and mounting method. Testing in your specific application is recommended.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 8 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 protection against moisture, oxidation, and everyday wear.
Can it be used outdoors?
Yes. For continuous 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, with the north and south poles located on the two circular ends.
