How It Works
The Magnetic Arm Band is a band embedded with super strong neodymium magnets to hold small metal objects right on your arm. A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is the most widely used type of rare earth magnet. Neodymium magnets are the strongest type of permanent magnet commercially available. They have replaced other types of magnets in the many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives, magnetic fasteners, and the magnetic arm band.
"A magnet is a piece of metal with a strong attraction to another metal object. The attraction a magnet produces is called a "magnetic field."
