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 manufacturing, engineering, robotics, automation systems, electronics, and custom magnetic assemblies.

How Strong Is This Magnet?

This N45 neodymium block magnet generates over 33 lbs of pull force under ideal conditions. Actual holding strength depends on steel thickness, surface finish, air gaps, temperature, and mounting configuration. With a Br Max rating of 13,500 Gauss, it delivers powerful magnetic performance in a compact block design.

Common Questions About This Magnet

How much weight can this magnet hold?

This magnet provides over 33 lbs of pull force under ideal conditions. Actual holding capacity depends on the steel surface, mounting method, and application design.

Is N45 stronger than N42?

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

Can this magnet be used outdoors?

The Nickel-Copper-Nickel coating provides good corrosion resistance, but additional protection is recommended for prolonged outdoor exposure.

Can it rust?

The protective nickel coating helps resist corrosion; however, moisture exposure and coating damage can eventually result in rust.

What direction is it magnetized?

This magnet is magnetized through the 3/8-inch thickness, with the north and south poles located on the two 3/4" x 3/4" faces.
