Inside MP Materials' "Independence" factory in Fort Worth, Texas, items that look like gum strips, corn flakes, and crushed pepper are laid out on a table. A giant U.S. flag hangs from the ceiling, and employees wearing protective thermal suits work near equipment where temperatures surpass 1,000 degrees Celsius. Under bright white lights, a shiny red Cadillac Vistiq gleams with its electric motor ripped open on a table, revealing what's inside: rare earth magnets.
The magnets are tiny, roughly equivalent to a miniature Hershey's candy. They feel robust and solid to hold, with smooth texture and sharp edges. Above all, their importance is hard to overstate. They're used in everything from military weapons and fighter jets to medical devices, iPhones, and electric vehicles.
