Product Overview
These 1" x 2" N42 Neodymium Cylinder Magnets are designed for applications requiring exceptional holding power and a deep magnetic field. The 1-inch diameter provides concentrated magnetic contact, while the extended 2-inch length creates a powerful magnetic field capable of producing approximately 180 pounds of pull force under ideal conditions. Their elongated cylindrical design provides excellent magnetic reach, making them ideal for demanding industrial and engineering applications.
Manufactured from premium N42 grade NdFeB (Neodymium-Iron-Boron), these rare earth magnets deliver reliable performance while providing greater magnetic strength than N40, N38, and N35 grades. They are commonly used in automation systems, heavy-duty magnetic fixtures, machinery, robotics, scientific equipment, and custom engineering projects where dependable magnetic force is essential.
Each magnet is finished with a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing excellent protection against corrosion, chipping, and everyday wear while maintaining a smooth, polished appearance.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a permanent magnet manufactured from NdFeB (Neodymium-Iron-Boron), the strongest commercially available magnetic material. Its cylindrical shape produces a concentrated magnetic field that extends beyond both flat ends, making it ideal for applications requiring deep magnetic penetration, powerful holding force, and stable alignment.
This magnet is axially magnetized (through its 2-inch height), meaning the north and south poles are located on the two circular faces.
How Strong Is This Magnet?
With an approximate 180-pound pull force, this N42 cylinder magnet delivers exceptional holding power when placed against a clean, thick steel surface under ideal conditions. Its extended length helps produce a deeper magnetic field, making it especially effective in industrial fixtures, machinery, magnetic separation, and engineering applications.
Actual holding strength depends on several factors, including:
-
Thickness and type of steel
-
Surface finish and cleanliness
-
Air gap between the magnet and steel
-
Mounting orientation
-
Temperature and operating environment
For critical applications, testing under actual operating conditions is recommended.

Common Questions About This Magnet
What is the pull force?
Approximately 180 pounds under ideal testing conditions.
Is N42 stronger than N35?
Yes. N42 provides noticeably greater magnetic energy and holding force than N35 magnets of the same dimensions.
Can it rust?
The nickel coating provides excellent corrosion resistance, but the magnet should not be left unprotected in wet or marine environments for extended periods.
Can it be used outdoors?
Yes. For long-term outdoor use, an additional protective coating or sealed housing is recommended.
What direction is it magnetized?
This magnet is axially magnetized, with the north and south poles located on the two circular faces.
Do you offer bulk discounts?
Yes. Volume pricing is available for manufacturers, distributors, OEMs, and large production orders.
