Permanent magnets are vital components in an enormous number of domestic and industrial devices. They are particularly crucial within the renewable energy sector, including the motors for electric vehicles.

The EU has begun objectives to remove, or greatly reduce, the need for heavy rare earths in permanent magnets.
