Thin, super-strong neodymium (N52) disc magnets made from the strongest magnetic material available to buy.
These thin neodymium disc magnets are little bigger than a watch battery but because they are made from the strongest magnetic material available to buy they produce an incredible pull. These magnets are so strong that they will wipe data from hard drives and are commonly used in large scale engineering projects where maximum strength is required. Each magnet is coated with three layers of nickel, copper and nickel to improve corrosion resistance and provide a smooth and clean finish. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully.
