Apple is investing $500 million over several years to purchase US-made rare earth magnets from MP Materials. These magnets will be used in various Apple products like iPhones and MacBooks, addressing increasing global demand. MP Materials is the sole fully integrated rare earth producer in the US. The partnership includes improvements to a Texas processing facility, adding manufacturing lines for Apple products and creating new jobs in advanced manufacturing and R&D. This move aligns with Apple's commitment to American innovation and strengthens its supply chain while supporting domestic job growth.
