| dc.description.abstract | The dataset includes a COMSOL model that replicates the experimental setup used for characterizing ferromagnetic hysteresis. Based on this model, synthetic training data were generated and used to create a surrogate model within COMSOL. This surrogate model was integrated into a MATLAB script that also processes experimental measurement data. The script performs an inverse identification of the Jiles–Atherton parameters using a Differential Evolution algorithm. This approach enables a model-based reconstruction of the ferromagnetic hysteresis curve for the investigated material. | en |
