Scientists at the University of New Hampshire used artificial intelligence to create a database of magnetic compounds. This could help reduce our reliance on rare earth elements and make electric vehicles more affordable.

Magnets are crucial components in many modern technologies, from smartphones to medical devices. However, most powerful magnets rely on rare earth elements that are expensive, imported, and hard to secure. A team of scientists at the University of New Hampshire has developed an artificial intelligence (AI) system to speed up the search for advanced magnetic materials. Their work has resulted in a searchable database containing 67,573 magnetic compounds, including 25 new materials that can stay magnetic at high temperatures.

The researchers used AI to read scientific papers and extract important experimental data. This information was then used to train computer models to determine whether a material is magnetic and calculate the temperature at which it loses its magnetism. The results were organized into one comprehensive and searchable database, called the Northeast Materials Database.

This breakthrough could help reduce our dependence on rare earth elements, lower the cost of electric vehicles and renewable-energy systems, and strengthen the US manufacturing base.

Why It Matters

As India aims to transition to cleaner energy sources and increase its use of electric vehicles, this research has significant implications for the country's energy sector. By reducing our reliance on rare earth elements, we can make electric vehicles more affordable and sustainable.
