N35 D40*20mm Neodymium Ndfeb Big Round Magnet

N35 D40*20mm Neodymium Ndfeb big round magnet This medium-sized neodymium disc magnet is made from ultra N35 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 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.
