Product Overview
These 1" x 1" N45 Neodymium Cylinder Magnets are designed for demanding applications requiring exceptional magnetic strength and reliability. With a 1-inch diameter and 1-inch height, they generate approximately 105 pounds of pull force under ideal conditions, making them suitable for heavy-duty industrial, commercial, and engineering applications.
Manufactured from premium N45 grade NdFeB (Neodymium-Iron-Boron), these cylinder magnets provide stronger magnetic performance than N42, N40, N38, and N35 grades while offering an excellent balance of strength and value. They are commonly used in industrial automation, magnetic holding systems, tooling, machinery, robotics, magnetic separators, and research applications where dependable magnetic force is essential.
Each magnet is protected by a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing excellent resistance to corrosion, scratches, and chipping while maintaining a smooth, polished finish. Manufactured in ISO-certified facilities, these magnets deliver consistent quality and long-lasting performance.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a permanent NdFeB (Neodymium-Iron-Boron) magnet made from an alloy of neodymium, iron, and boron. Neodymium magnets are the strongest commercially available permanent magnets and are widely used in manufacturing, robotics, engineering, automation, scientific instruments, and industrial equipment.
This magnet is magnetized through its 1-inch thickness (axially magnetized), placing the north and south poles on the two flat circular faces. This orientation provides maximum holding force and a deep magnetic field, making cylinder magnets ideal for heavy-duty magnetic assemblies and precision applications.
How Strong Is This Magnet?
This 1" x 1" N45 cylinder magnet delivers approximately 105 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.
Actual holding force depends on several factors, including:
- Surface material
- Steel thickness
- Contact area
- Air gap
- Mounting method
- Environmental conditions
For maximum holding performance, use this magnet against a clean, flat, thick steel surface.

Common Questions About This Magnet
What is the pull force?
Approximately 105 pounds under ideal testing conditions.
Is N45 stronger than N35 magnets?
Yes. N45 provides significantly greater magnetic strength and holding power than N35 magnets of the same size.
Can it rust?
The Nickel-Copper-Nickel triple-layer coating provides excellent corrosion resistance. If the coating becomes damaged, exposure to moisture may eventually cause corrosion.
Can it be used outdoors?
Yes. Additional sealing is recommended for prolonged outdoor exposure or marine environments.
What direction is it magnetized?
This magnet is axially magnetized through its 1-inch thickness, with the magnetic poles located on the two flat circular faces.
