What Are the Primary Uses of Neodymium Magnets?
Neodymium magnets are used wherever a strong magnet has to fit in a small space. Their primary jobs are electric motors and generators (cordless tools, EVs, wind turbines), sound (speakers, earbuds), sensing and data (hard drives, position sensors), holding and closures (cabinets, bags, packaging), separating metal from food and products, and medical imaging.
Six Jobs Neodymium Magnets Do
Make Motion
Electric motors in cordless tools, fans, drones, e-bikes and electric vehicles.
Make Electricity
Generators in wind turbines and hand-crank devices.
Make Sound
Speakers, headphones, earbuds and phone receivers.
Sense and Store
Hard drives, position and speed sensors, alarm switches.
Hold and Close
Cabinet catches, purse and bag closures, Display Boards, packaging.
Separate and Clean
Grate Magnets pull metal contaminants out of food, plastics and powders.
Why Neodymium?
As neodymium magnets have become less expensive since the 1980s, they’ve replaced larger ferrite and alnico magnets in many products. A smaller magnet means a smaller, lighter motor, speaker or device.
