rust.
Ordinary neodymium magnets only use one side of their magnetic field to stick to metal which means they’re only using half of their available strength. However,if add a steel cup, the other pole of the magnet to be used which increases the strength of the magnet to much higher than that of a normal neodymium magnet but also makes the other side magnetically weak.
