Need to know how much force your magnet can handle? Our easy-to-use pull force calculator helps you determine the approximate strength your magnet can exert, based on size, shape, and material. Whether you're designing a project or just curious, we're here to help you make the most of your magnets!

Important information to know: Magnetic calculators use approximation formulas. These formulas become less accurate as magnet sizes decrease. Please use with caution, especially with smaller magnets.

For questions or requests involving custom magnets or assemblies, please visit our SM Magnetics website or go directly to our Custom Magnet Request Page, where you can upload your print.
