Uses for our rare earth ring magnets

Neodymium magnets like this ring-shaped item have unique advantages that other shapes cannot rival. The hole inside the Ring creates an attachment point for use in technical products and in electronic equipment manufacturing, where the magnet can sit atop plastic mouldings or on shafts that allow the ring to move and react with circuitry and electric fields. Neodymium Ring magnets are found in nearly all modern devices and equipment because they are small, powerful, permanent, reliable and because they eliminate the need for mechanical parts that can prove to be unreliable and will fail over time. This Ring is manufactured in N42 Grade material for increased magnetic strength. Higher grades are often used with Ring magnets to compensate for the loss of overall volume, and hence magnetic strength, that the void area creates.
