Neodymium magnets are generally neodymium , iron and boron composition , requiring coating, not only because such a magnet is very fragile, and because iron is exposed is oxidized in air. Standard neodymium coating there is a problem that can not achieve a harmonious effect with Apple's design aesthetics . Document states : " We therefore wanted a magnetic surface coating, this coating with the overall appearance of the device , to match the shape and feel ." Patent document how to use has been described as an aluminum coating , which comprises the use of " diamond saws and electrical discharge machining equipment" and other cutting tools for the neodymium magnet plastic, so that it becomes available for Apple's MacBook laptop and iPad tablet computer integrated aluminum enclosure specifications.
