Using Experimental Data and Differential Evolution to Model and Understand Magnetic Hysteresis

Standard hysteresis measurement methods are challenging to implement in industrial environments due to their time consuming and cost intensive nature. By employing a U shaped soft magnetic yoke in an attachment technique on ferromagnetic materials, the combined/ superimposed hysteresis of the yoke and the sample can be measured. The primary challenge lies in separating the superimposed hysteresis. By integrating experimental data with Matlab in COMSOL simulations, the superimposed hysteresis can be decoupled using an evolutionary algorithm, allowing for the precise determination of the sample material's hysteresis.
