Product Overview
These 3/4" x 3/4" N42 Neodymium Cylinder Magnets deliver exceptional holding power in a compact cylindrical design. The 3/4-inch diameter provides excellent magnetic contact, while the 3/4-inch height creates a deep magnetic field capable of producing approximately 52 pounds of pull force under ideal conditions. Their balanced dimensions make them well suited for applications requiring both concentrated holding force and compact size.
Manufactured from premium N42 grade NdFeB (Neodymium-Iron-Boron), these magnets provide significantly greater magnetic strength than N40, N38, and N35 grades. They are commonly used in industrial machinery, magnetic tooling, robotics, automation systems, engineering prototypes, magnetic separators, and heavy-duty workshop projects where dependable performance is essential.
Each magnet is protected with 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 service life.
What Is a Neodymium Cylinder Magnet?
A neodymium cylinder magnet is a permanent NdFeB (Neodymium-Iron-Boron) magnet manufactured from an alloy of neodymium, iron, and boron. Neodymium magnets are the strongest commercially available permanent magnets and are widely used throughout manufacturing, engineering, robotics, automation, scientific equipment, and industrial applications.
This magnet is magnetized through its 3/4-inch thickness (axially magnetized), placing the north and south poles on the two flat circular faces. This magnetic orientation maximizes holding power while creating a deep magnetic field, making cylinder magnets ideal for precision positioning, magnetic fixtures, tooling, and industrial assemblies.
Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 3/4" x 3/4" N42 cylinder magnet delivers approximately 52 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.
Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be verified for your intended application.

Common Questions About This Magnet
What is the pull force?
This magnet provides approximately 52 pounds of pull force under ideal testing conditions.
Is N42 stronger than N35 magnets?
Yes. N42 delivers significantly greater magnetic strength and holding power than N35 magnets of the same dimensions.
Can it rust?
The Nickel-Copper-Nickel triple-layer coating provides excellent protection against corrosion. If the coating becomes damaged and moisture reaches the magnet, corrosion may occur over time.
Can it be used outdoors?
Yes. However, additional sealing is recommended for prolonged outdoor exposure, marine environments, or high-humidity conditions.
What direction is it magnetized?
This magnet is magnetized through its 3/4-inch thickness (axially magnetized), with the north and south poles located on the two flat circular faces.
