What Are Neodymium Magnets Used For?

Since Neodymium Magnets' invention in the early 1980s, a wide range of industries has found uses for these super strong magnets. If you’re reading this on your computer, you’re using a neodymium magnet right now! Some applications include:

Hard disk drives – A hard disk has tracks and sectors that contain magnetic cells; these cells are magnetized when data is written to the drive.

Microphones, headphones and loudspeakers – current-carrying coils are used with permanent magnets to convert electricity into mechanical energy that changes the pressure of the surrounding air to create sound.

Dentures – To keep dentures securely in place, tiny neodymium magnets are used.

Door catches – Commercial and residential buildings often use doors with neodymium magnetic catches.

Magnetic jewelry – Magnetic therapy jewelry is often made with neodymium magnets; these magnets are also used in bracelet and necklace clasps.

Anti-lock brake sensors – If you have anti-lock brakes in your car, they utilize neodymium magnets wrapped inside copper coils in their sensors.
