What Is a Neodymium Block Magnet?
A neodymium block magnet is a rectangular rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Block magnets provide exceptional holding force and a large contact surface area, making them ideal for industrial equipment, manufacturing fixtures, engineering projects, robotics, automation systems, and custom magnetic assemblies.
How Strong Is This Magnet?
This N52 neodymium block magnet generates over 36 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, alignment, and mounting configuration. With a Br Max rating of 14,400 Gauss, it delivers exceptional magnetic performance in a compact and versatile package.

Common Questions About This Magnet
How much weight can this magnet hold?
This magnet provides over 36 lbs of pull force under ideal conditions. Actual holding capacity depends on surface material, air gaps, alignment, and installation method.
Is N52 stronger than N42?
Yes. N52 magnets provide significantly greater magnetic energy and holding force than N42 magnets of the same dimensions.
Can this magnet be used outdoors?
The Nickel-Copper-Nickel coating offers excellent corrosion resistance. For extended outdoor use or harsh environments, additional sealing is recommended.
Can it rust?
The protective nickel coating helps resist corrosion; however, prolonged exposure to moisture or coating damage can eventually result in rust.
What direction is it magnetized?
This magnet is magnetized through the 1/4-inch thickness, with the north and south poles located on the 1" x 1" faces.
What is the maximum operating temperature?
This magnet is rated for continuous operation up to 176°F (80°C). Exposure to higher temperatures may permanently reduce magnetic strength.
