Revolutionary rare-earth-free magnet created: why it matters

From home computers to magnetic suspension trains, from power tools to MRI devices — rare earth permanent magnets surround us everywhere. Without them, modern life would be more difficult, so their importance cannot be overestimated. But the extraction of rare earth elements, of which they are composed, is often a very difficult and energy-consuming task. Therefore, scientists were looking for ways to create magnets without such elements and they succeeded, writes IFLScience.

The British company Materials Nexus, in collaboration with scientists from the Henry Royce Institute and the University of Sheffield (Great Britain), created a new magnet called MagNex.

This is a permanent magnet that does not contain rare earth elements and is made of materials whose cost is only 20% of the cost of conventional permanent magnets.

The creation of the new magnet also made it possible to reduce carbon dioxide emissions by 70%, in terms of kilograms of CO2 per kilogram of material, compared to rare-earth permanent magnets.

< p>Permanent magnets that exist today were created from rare earth alloys in the 70s — 80s of the last century. The search for elements with the required properties and development took a very long time. But the process of creating a new MagNex magnet from the project stage to its verification took 200 times less time.

The fact is that the developers of the new magnet connected artificial intelligence (AI) to the search for the necessary materials. According to the scientists, this achievement shows a bright future for materials science and manufacturing.

AI analyzed the composition of more than 100 million potential alloys that are needed to create a permanent magnet and should not contain rare earth elements. Scientists believe that such a hike has a huge potential for creating new materials. The authors of the new magnet call their development “revolutionary”.

Scientists believe that this approach to creating new materials can help achieve zero carbon dioxide emissions and minimize the need for rare earth elements.
