How Air Gap, Workpiece Conditions, and Operating Temperature Affect Magnetic Pull Force

In sizing and selecting magnets and custom magnetic assemblies, it is important to ask a number of questions about the working area in which the magnet will operate. The answers to these questions help deliver a higher level of success in providing a magnet that meets the fit, form, and function of the application. Three areas of concern that we’ll address are: air gap relative to holding force, workpiece conditions, and operating temperature. All of these represent important conditions for the magnet’s ultimate performance…
