As part of our ongoing effort to provide magnet-related resources that may be useful to those in the field, we have added to our collection of magnetic property calculation tools. This particular resource is a magnetic force calculation utility that aids in estimating the attractive (pull) force of Samarium Cobalt magnets.
This new magnetic calculator can be found here: SmCo Pull Force Calculator
Similar to our Neodymium magnet pull force calculator, this particular calculator allows engineers to vary the size, shape, and material grade to estimate the attractive force (in lbf) of a Samarium Cobalt magnet in direct contact with a flat, sufficiently thick, steel work-piece. The Samarium Cobalt pull force calculator provides calculations for SmCo magnet grades from 16MGOe (1-5) to 32MGOe (2 – 17). The calculator also allows users to specify the calculated magnet shape between Disc / Cylindrical and Square / Rectangular magnet geometry.
The resulting force presented by the calculator is an estimate meant to aid engineering professionals in the early stage design of magnetic applications. This calculator’s results should be viewed as “first order” and not used as the primary data for product realization. This is because many additional variables exist in the real world that need to be taken into account to obtain truly accurate magnetic pull force calculations. 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 this new Samarium Cobalt magnetic pull-force calculation tool proves useful. As always, we will continue to expand our available magnetic engineering resources.
