The Magnet Test. Like silver and gold, real copper does not have much magnetism. "Just like real silver, copper is only very slightly magnetic," Martin says. "You can conduct the same magnet test by placing a magnet on the surface of the item. If the magnet sticks, you can make sure that the item isn't copper."

Copper is a non-ferrous metal. It doesn't contain iron, so it won't turn into rust when exposed to oxygen. Instead, when oxygen molecules land on copper's surface, they combine with copper atoms and form copper oxide. Unlike iron oxide, copper oxide does not disintegrate over time.
