Automated Identification of the Origin of Energy Loss in Non-Oriented Electrical Steel by Feature-Extended Ginzburg–Landau Free-Energy Framework

Published in Research Square (Preprint), 2024

This preprint presents an interpretable, physics-informed machine learning framework based on a feature-extended Ginzburg–Landau free-energy model for analyzing energy loss mechanisms in non-oriented electrical steel.

Using a combination of simulation data and persistent topological features, the study offers a new method to automatically identify the origin of loss components, with relevance to industrial material development and magnetic systems research.
