Neodymium magnets (also known as "NdFeB", "Neo" or "Nd" magnets) are permanent magnets made primarily of neodymium, iron, and boron. They are from the family of rare earth magnets and have the highest magnetic properties of all permanent magnets, stronger than samarium cobalt (SmCo), alnico, and ferrite. In addition to their high magnetic strength, they are relatively inexpensive, making them ideal for a wide range of consumer, commercial, industrial, and technical applications.

　　Neodymium magnets (NdFeB) provide maximum performance with minimum magnet volume. They should always be coated to prevent corrosion risk - NiCuNi, Zinc, NiCuEpoxy, and Gold are popular finishes. Class 55 NdFeB magnets are commonly used. They are used in virtually all industries: automotive, aerospace, wind turbines, military, white goods, lighting, food preparation, separation, motor, and generator industries are just a few examples of industries.

　　Since their invention in the early 1980s, these super-strong magnets have been used in a wide variety of industries. If you're reading this on your computer, you're using neodymium magnets right now! Some applications include:

　　Hard Disk Drives - Hard disks have tracks and sectors that contain magnetic cells; these cells are magnetized when data is written to the drive.

　　Microphones, Headphones, and Speakers - Current-carrying coils are used with permanent magnets to convert electrical energy into mechanical energy, which changes the pressure of the surrounding air to produce sound.

　　Dentures - To hold dentures securely in place, tiny neodymium magnets are used. In fact, neodymium magnets are used in a variety of medical devices. Read more about neodymium magnets in medical applications here.

　　Door Locks - Commercial and residential buildings often use doors with neodymium magnetic latches.

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

　　Anti-lock brake sensor - If your car has anti-lock brakes, they use a neodymium magnet wrapped in a copper coil in the sensor.
