AI Develops "Ground-Breaking" New Magnet Free Of Rare Earth Metals

Jun 21, 2024 - iflscience.com
Materials Nexus, in collaboration with the Henry Royce Institute and the University of Sheffield, has developed a new magnet, MagNex, which is free of rare earth elements. The magnet is made from materials costing one-fifth of regular permanent magnets and has 70% less carbon emissions. The development process was 200 times faster than traditional methods, thanks to a machine learning algorithm that analyzed over 100 million potential alloys.

This breakthrough could have significant implications for renewable energy and low-carbon transport, as it eliminates the need for rare earth elements in high-performance permanent magnets. The AI-driven approach also opens up enormous potential for the creation of new materials, highlighting the increasing role of AI in materials discovery and manufacturing.

Key takeaways:

  • A machine learning algorithm has helped develop a new magnet, MagNex, which is free of rare earth elements.
  • The materials used to produce MagNex cost one-fifth of those used in regular permanent magnets, and its production results in a 70 percent reduction in carbon emissions.
  • The AI system used in the development of MagNex can identify and analyze the composition of over 100 million potential alloys that could be used to create a permanent magnet.
  • This breakthrough could have a significant impact on renewable energy and low-carbon transport by eliminating the need for rare earth elements in high-performance permanent magnets.
