Rare-earth permanent magnets provide the rotor field in compact joint motors. Neodymium-based magnets deliver high magnetic strength in a small volume; dysprosium or terbium additions improve resistance to demagnetisation at higher temperatures. Motor production therefore depends on separated oxides, metal and alloy conversion, and finished magnet capacity. The IEA identifies magnet manufacturing and conversion of oxides into metals as major bottlenecks in expanding supply outside China.

MP Materials expands US magnet manufacturing
Fort Worth / Northlake, Texas
MP Materials reported further magnet deliveries for customer qualification at its Independence plant. Construction of its 10X campus in Northlake, Texas, was underway. The campus is planned to bring total company magnet capacity to about 10,000 tonnes a year, with commissioning starting in 2028.
Sources
The 10,000-tonne figure is planned company-wide capacity for finished NdFeB magnets. Independence remained in customer qualification in the August update.

USA Rare Earth adds metal and magnet capacity
Stillwater, Oklahoma / Blacksburg, South Carolina
USA Rare Earth commissioned its first Stillwater magnet line in March 2026 and retained a 600-metric-tonne annual run-rate target for Q4. It broke ground at Blacksburg in September. That plant targets 6,400 tonnes/year of sintered magnets and 5,000 tonnes/year of strip-cast metal and alloy, with commissioning starting in 2028.
Sources
Stillwater’s 600-tonne run rate and Blacksburg’s capacities are company targets.
