Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Approximately 2.4 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 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? |
Precision alignment, embedded magnetic mounts, magnetic closures, woodworking, resin projects, electronics, crafts, and DIY applications. |
Product Overview
The N52 Neodymium Cylinder Magnet 3/16" x 3/16" offers exceptional magnetic performance in a perfectly balanced cylindrical design. With both its diameter and length measuring 3/16 inch, this compact magnet provides consistent magnetic performance, making it ideal for precision alignment, locating pins, embedded installations, and compact mechanical assemblies.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these rare earth magnets deliver maximum magnetic strength for their size. Their higher magnetic energy provides a noticeably stronger hold than lower-grade magnets, making them an excellent choice for woodworking, electronics, robotics, engineering projects, and product development where every bit of holding power counts.
Each magnet features a durable Nickel-Copper-Nickel triple-layer coating that helps resist corrosion while maintaining a smooth, polished appearance. Supplied in a convenient 100-piece pack, these magnets are ideal for manufacturers, engineers, woodworkers, hobbyists, and DIY enthusiasts who require reliable, high-performance magnets for repeated use.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a rod-shaped permanent magnet made from neodymium, iron, and boron (NdFeB). Unlike flat disc magnets, cylinder magnets provide greater magnetic depth and are commonly used in embedded applications, alignment systems, positioning fixtures, magnetic latches, and precision assemblies.
Their symmetrical shape makes them especially well suited for drilled-hole installations, molded components, resin castings, and compact mechanical designs where consistent alignment is important.
How Strong Is This Magnet?
This N52 cylinder magnet generates approximately 2.4 pounds of pull force under ideal conditions against a thick, flat steel surface. Its premium N52 magnetic grade provides the highest magnetic energy available in standard neodymium magnets, allowing it to deliver exceptional holding power despite its compact dimensions.
Because cylinder magnets have a relatively small contact surface, actual pull force may vary depending on the application, mating surface, air gap, and mounting conditions. Testing in your specific application is recommended.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 2.4 pounds of pull force under ideal conditions. Actual holding force may vary depending on the contact surface and application.
Is N52 stronger than N35?
Yes. N52 is the highest standard neodymium magnet grade and provides significantly greater magnetic strength than N35 magnets of the same dimensions.
Can it rust?
Like all neodymium magnets, the core material can corrode if left unprotected. The Nickel-Copper-Nickel triple-layer coating provides excellent protection against corrosion 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 magnet is axially magnetized through its length, 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, and OEM customers.
