Protected by a durable Nickel-Copper-Nickel triple-layer coating, this magnet offers excellent resistance to corrosion and wear while maintaining a clean, professional appearance. ISO-certified manufacturing ensures consistent quality and superior magnetic performance for industrial, commercial, and personal applications.

What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular or square-shaped rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). These magnets provide exceptional magnetic strength relative to their size and are commonly used in manufacturing, engineering, robotics, electronics, product development, and custom magnetic assemblies.

How Strong Is This Magnet?

This N52 neodymium block magnet produces approximately 9.2 pounds of pull force under ideal conditions. Actual holding strength depends on factors such as steel thickness, surface conditions, air gaps, temperature, and mounting configuration. With a BrMax rating of 14,500 Gauss, this magnet provides maximum magnetic performance and is stronger than N50, N48, N45, N42, N40, N38, and N35 magnets of the same size.

Common Questions About This Magnet

How much weight can this magnet hold?

Under ideal conditions, this magnet generates approximately 9.2 lbs of pull force. Actual holding capacity depends on the surface material, thickness, and application design.

Is N52 stronger than N42?

Yes. N52 magnets offer significantly greater magnetic energy and holding power than N42 magnets of the same dimensions.

Can this magnet be used outdoors?

The nickel coating provides good corrosion resistance, but additional protection is recommended for long-term outdoor exposure.

Can it rust?

The Nickel-Copper-Nickel coating helps protect against corrosion; however, prolonged exposure to moisture or damage to the coating can eventually result in rust.

What direction is it magnetized?

This magnet is magnetized through the thickness (1/8"), with the north and south poles located on the two 1/2" x 1/2" faces.
