Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 18 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 strongest commercially available neodymium grade and provides substantially greater holding power than N35 magnets of the same size. |
| Can it be used outdoors? |
Yes, but additional sealing is recommended for long-term exposure to moisture or harsh environments. |
| What is it commonly used for? |
Precision alignment, embedded mounting, magnetic closures, woodworking, industrial assemblies, and DIY projects. |
Product Overview
These 3/8" x 3/8" N52 Neodymium Cylinder Magnets deliver exceptional magnetic strength in a compact, perfectly balanced cylindrical shape. With equal diameter and height, they fit neatly into drilled holes and provide accurate alignment for assemblies where both precision and holding power are essential.
Manufactured from premium N52 rare earth neodymium, these magnets produce outstanding magnetic performance while remaining versatile enough for countless industrial, commercial, and DIY applications. Their compact design makes them ideal for woodworking, fixtures, embedded mounting, magnetic closures, and custom fabrication projects.
Each magnet is protected by a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing excellent resistance to corrosion, scratching, and chipping while maintaining a smooth, polished finish.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a permanent magnet made from NdFeB (Neodymium-Iron-Boron), the strongest commercially available magnetic material. Unlike disc magnets, cylinder magnets have a greater height relative to their diameter, allowing them to provide increased magnetic depth while maintaining a compact footprint.
These magnets are magnetized through their height (thickness), placing the north and south poles on the two flat circular ends. Their shape makes them ideal for precision positioning, embedded installations, sensors, fixtures, and mechanical assemblies.
How Strong Is This Magnet?
This 3/8" x 3/8" N52 cylinder magnet delivers approximately 18 pounds of pull force under ideal testing conditions using a thick, clean steel surface.
Because cylinder magnets have a relatively small contact area, actual pull force may vary depending on the thickness, flatness, and material of the steel surface. Testing in your specific application is recommended to determine real-world performance.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 18 pounds of pull force under ideal conditions. Actual pull force may vary depending on the application and contact surface.
Is N52 stronger than N35?
Yes. N52 offers significantly greater magnetic energy and holding strength than N35 magnets of the same dimensions.
Can it rust?
Like all neodymium magnets, it contains iron and may corrode if the protective coating is damaged or exposed to harsh environments for extended periods.
Can it be used outdoors?
Yes, but additional sealing is recommended for long-term outdoor or marine applications.
What direction is it magnetized?
This magnet is magnetized through its thickness (height), with the north and south poles located on the two flat circular ends.
