Industrial Heavy-Duty Neodymium Magnet Information:

Common questions and answers about using industrial heavy-duty magnets.

What do Industrial Heavy-Duty Neodymium Magnet grades mean?

Magnet Grades are a way of classifying what material the magnet is made of, how strong a magnet is and the maximum operating temperature a magnet can withstand before losing its magnetism.

For neodymium magnets, the “N” stands for neodymium, the primary rare-earth element used in the magnet. The grade numbers after the “N” indicate the maximum energy product—the higher the number, the stronger the magnet. The letters after the grade number indicate the magnet can operate at a higher temperature than a standard grade without losing its magnetism.

We offer Industrial Heavy-Duty Neodymium Magnets in grades N38, N42, N42M and N52.

I need a really strong magnet! How do I figure out what Industrial Heavy-Duty Magnet to buy?

To choose the right magnet, you need to know the required pull force for your project or application. The Magnet Pull Force represents how strongly a magnet can attract to and hold onto a surface. Magnet pull force is the maximum force required to pull a magnet vertically away from a ferrous (steel) plate.

Our Industrial Heavy-Duty Neodymium Magnets have Pull Forces ranging from 1.19 lb to 500 lb depending on the specific magnet. The Pull Forces of a magnet can be found under the Product Details tab in every magnet product page.

An Industrial Heavy-Duty Neodymium Magnet’s listed pull force is based on controlled lab testing and represents ideal conditions, so real-world performance can vary depending on how the magnet is used. Factors like surface type, friction, distance (gaps), magnet thickness, the weight of the object being mounted/attached, and whether it’s attached to steel, another magnet, or used vertically can significantly affect a magnet’s holding strength. To learn more about how we test any why we only list maximum pull force, see our Testing Magnet Strength article. To get the best results, we recommend experimenting with and testing out different magnets to match your specific application.

Explore our convenient Magnet Pull Force Calculator to calculate magnetic pull forces needed for your project or application.
