Neodymium Disc Magnet

Most people are aware of magnets in the form of low strength, flexible magnets that have printed advertising and are used to attach papers and other items to the household refrigerator. Neodymium magnets in their various shapes and grades have very little in common with those weaker ferrite based fridge magnets, except that they are also magnetic. Even small Neodymium disc magnets are extremely strong and able to hold many times their own weight. Thin,round magnets like this Neodymium disc rely on the rare earth materials beneath the silvery nickel coating to generate extremely strong magnetic hold. The silver coating is both attractive and practical in that it contains the powdery rare earth material that may otherwise cause the devices with magnetic components to malfunction. Clean, dust-free surfaces and conditions are important for the operation of electronic goods and where sterile environments need to be maintained. The coating also allows epoxy glue to be used to attach magnets to your favourite hobby or craft project. Super strong rare earth disc magnets have constant and permanent holding power that is utilised in a wide range of industrial equipment and processes that include mobile phones, electric motors, power tools, waste recycling and water treatment.
