This magnet is smaller than a block of post-it notes but incredibly produces an astonishing pull of 32.2kg. These magnets are so strong that they will wipe data from hard drives and are commonly used in large scale engineering projects such as wind turbines. Each magnet has a triple coating of nickel, copper and nickel again to reduce corrosion. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully.
