Magnets and Rare Earths
Every robot joint motor depends on neodymium-iron-boron magnets, the strongest available for their weight. This learning path walks through what goes into a magnet, how it travels from mine to refinery, where neodymium is found, and why export controls matter now. One figure stands out: in 2024, China produced roughly 94% of the world's sintered magnets.
Every joint motor needs a magnet, what it is made of, and who makes nearly all of them.
