Magnetic Pull Force Explained


Breakaway force, holding force, fixturing force – “How can all of these represent the same measurement?” a younger engineer recently inquired. Engineers and non-engineers alike can be puzzled trying to understand some of the commonly used – but potentially misinterpreted terms – related to the concept of a magnet’s pull force.

These phrases are often used to represent “strength” when writing magnetic specifications. They also may be mentioned when anticipating the work required of a magnet within an application. To add to the potential confusion, maximum holding force or how much tensile force is exerted by any magnet, is often shown in online calculators – like our neodymium pull force calculator – are based on theoretical calculations of flux density.

Did You Know?

When designing near the limits of a magnet’s max operating temperature, knowing your magnet’s load line is extremely important.
