Ames Lab 101: Rare-earth Magnets

See video

Ames Laboratory senior scientist Bill McCallum talks about controlling the element cerium for use in rare-earth magnets. McCallum is working to develop a rare-earth magnet that uses more abundant cerium in place of neodymium. McCallum's work is being funded through a recent grant by ARPA-E, the Department of Energy's advanced research agency.
