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 N42 neodymium cube magnet produces an approximate pull force of 3.7 pounds under ideal conditions. Despite its small size, it offers significantly greater magnetic strength than ceramic or ferrite magnets and outperforms lower-grade neodymium magnets such as N35 and N38 of the same dimensions.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet has an approximate pull force of 3.7 lbs under ideal conditions with direct contact to a thick steel surface.

Is N42 stronger than N35?

Yes. N42 magnets offer noticeably greater magnetic energy and holding force than N35 magnets of the same size.

Can this magnet be used outdoors?

The gold coating provides corrosion resistance, but prolonged exposure to moisture or harsh environments is not recommended without additional protection.

Can it rust?

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

What direction is it magnetized?

This magnet is magnetized through the thickness.

Do you offer wholesale pricing?

Yes. Applied Magnets offers wholesale and bulk discounts for larger orders. Contact us for a custom quote.
