rare earth magnets
Powerful lanthanide attractors
Rare earth magnets are powerful permanent magnets made from alloys of rare earth elements—typically neodymium or samarium-cobalt.
They produce magnetic fields far stronger than conventional iron or ceramic magnets despite their small size: The hard drive uses tiny rare earth magnets to position the read head.
They're found in headphones, electric motors, wind turbines, and countless electronic devices.
