This large disc magnet is made super-strong N52 grade neodymium and produces an incredible magnetic 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 should only be handled by people who are used to handling strong magnets and once a thorough risk assessment has been undertaken.
