Every magnet is designed to provide consistent magnetic performance and long-lasting durability while meeting demanding industrial and commercial requirements.

Featuring a Nickel-Copper-Nickel triple-layer coating for superior corrosion resistance, these N45 magnets are ideal for manufacturing, engineering, electronics, robotics, research, educational, and DIY applications. Their compact size and high magnetic strength make them a versatile solution across numerous industries.

What Is a Neodymium Block Magnet?

A neodymium block magnet is a rectangular or cube-shaped rare earth permanent magnet made from neodymium, iron, and boron (NdFeB). Block magnets provide strong holding force and a large contact surface, making them ideal for industrial, engineering, manufacturing, and DIY applications.

How Strong Is This Magnet?

This N45 neodymium block magnet produces approximately 4 pounds of pull force under ideal conditions when attached directly to a thick steel surface. Thanks to its higher N45 grade, it offers greater magnetic performance than comparable N42, N40, N38, and N35 magnets of the same dimensions. Actual pull force may vary depending on the application and surface conditions.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet generates approximately 4 lbs of pull force under ideal conditions on a thick, flat steel surface.

Is N45 stronger than N42?

Yes. N45 magnets provide higher magnetic energy and greater holding force than N42 magnets of the same size.

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating offers excellent corrosion resistance. However, prolonged exposure to moisture and harsh environments should be avoided.

Can it rust?

Neodymium magnets contain iron and may corrode if the protective coating becomes damaged.

What direction is it magnetized?

This magnet is magnetized through the thickness.
