Magnetic or non-magnetic?
A magnet attracts some materials. These are called magnetic materials: iron, steel (which is mostly iron), nickel and cobalt. Most other materials are non-magnetic, and that includes most metals, such as aluminium, copper, brass, gold and silver. So "it is a metal" does not mean "it is magnetic": you have to test it.
