In addition to providing a growing collection of informational articles related to magnetics in our TechTalk blog, we strive to make other beneficial magnet related resources available. To that end, we are pleased to announce the release of a pull force calculation tool for Neodymium Magnets. This magnetic force calculation utility can be used to help in estimating the attractive force of Neo magnets.
This new magnetic calculator can be found here: Neo Pull Force Calculator
This calculator allows engineers to estimate the attractive force (in lbf) of a Neodymium magnet in direct contact with a flat, sufficiently thick, steel work-piece. Properties that can be specified in the calculation include magnet size, shape, and material grade. Calculations can be obtained for NdFeB magnet grades from 28MGOe (Br 10,400 Gauss) to 52MGOe (Br 14,400 Gauss). Magnet shapes that can be specified include Disc / Cylindrical and Square / Rectangular.
Because several additional variables exist in the real world that need to be accounted for to determine truly accurate magnetic pull forces in various scenarios, this calculator’s results should only be viewed as “first order” rather than used as the primary data for product realization. Resulting forces obtained by this calculator are only estimates meant to aid engineering professionals in early design stages of magnetic applications. As with any magnet-related engineering project, we recommend that you consult with a qualified magnetic design engineer for design path assistance.
We hope that you find this NdFeB magnetic pull-force calculation tool to be helpful, and we plan to add more tools like it for other magnet materials in the future.
