Uses for our rare earth disc magnets:

Neodymium Discs are easily fitted into other products with very little consequence to the operation of these products. In fact, they are often used to improve the performance or appearance of many modern products or artistic works. They are sometimes retrofitted or otherwise incorporated into the early product design stage where they are used to create magnetic joins between component parts or even act as switches that operate electrical systems. This small and powerful Neodymium disc has been designed with a highly practical 3M adhesive backing so it can be applied to various materials, surfaces and circumstances. The magnet can attach to non-ferrous items so they become compatible with metal surfaces in the kitchen, shed or office.
Home and commercial maintenance problems can often be solved with the application of a strong yet unobtrusive Neodymium Disc magnet. Tradespeople and maintenance workers find countless ways to use these strong Neodymium disc magnets during their workday. Scale model makers are constantly finding new ways to apply magnetic bond to help their projects appear more lifelike or to operate more practically. Magnetic power is permanent under most conditions which makes these disc magnets a highly cost-effective alternative to the more traditional fastening systems.
