No energy transition without magnets: They are indispensable for electric motors, wind turbines and industrial applications such as robotics. However, their production is heavily dependent on rare earths. Against this backdrop, researchers and industry representatives discussed material innovations, recycling strategies and the reduction of raw material dependencies. "We are here today because we want to save the world, at least the European world of permanent magnets," said Prof. Dr. Gerhard Schneider, member of the IMFAA Executive Board, at the opening.
Research and application along the value chain
The focus of the magnet conference was on specialist presentations along the value chain. Researchers from Aalen University of Applied Sciences, Pforzheim University of Applied Sciences and TU Darmstadt presented new material science approaches. Prof. Dr. Dagmar Goll from Aalen University of Applied Sciences, Prof. Dr. Carlo Burkhardt from Pforzheim University and Prof. Dr. Oliver Gutfleisch from TU Darmstadt gave an overview of current research activities on magnetic materials. Prof. Dr. Jeffrey Snyder from Northwestern University in Illinois contributed international perspectives: he showed how AI-supported material discovery and automated high-throughput laboratories are accelerating the development of new magnetic materials. Industry representatives also provided insights into current challenges: Dr. Matthias Katter from VACUUMSCHMELZE emphasized the central role of permanent magnets for decarbonization and electrification. Dr. David Schuller from the ZF Group referred to the growing complexity in the development of new magnet compositions and challenges in supply chains. Dr. Mario Schönfeldt from the Fraunhofer Institute IWKS presented recycling. Dr. Bernd Grieb from ppm materials presented a geopolitical view of the raw materials situation for rare earths.
Insights into research and expert networks
The conference was complemented by a one-and-a-half-day training course with 30 participants, which covered the basics, manufacturing processes and current issues in magnet technology. Laboratory tours at Aalen University of Applied Sciences provided insights into magnetic materials research and modern characterization methods.
The Permanent Magnets Expert Group of the DGM's Joint Powder Metallurgy Committee also met during the Magnet Days. The committee, headed by Prof. Dr. Gerhard Schneider, is working on identifying measures for more technological sovereignty and innovative strength in Europe in the field of permanent magnets.
The Magnets Days were a successful premiere for Aalen University of Applied Sciences. The organization alternates between the research locations of Aalen, Pforzheim and Darmstadt under the coordination of the DGM. The next event will take place at Pforzheim University of Applied Sciences in 2027.
