A natural magnet is a magnet that occurs naturally in nature. All natural magnets are permanent magnets, meaning they will never lose their magnetic power.
Natural magnets can be found in sandy deposits in various parts of the world. The strongest natural magnet material is lodestone, also called magnetite. This mineral is black in color and very shiny when polished. The lodestone was actually used in the very first compasses ever made. Because natural magnets are permanent magnets, if lodestone is allowed to freely spin, its north pole will always align itself with the Earth's geographic north pole.
Today, if you visit a gem and mineral show, you'll find lodestones on display. Play with them and you'll see just how strong their magnetism is. A single lodestone can lift a string of a dozen or so other lodestones into the air.
There are other minerals that are natural magnets, but they are weak magnets so they won't be able to lift too much metal. Some of these are pyrrhotite, ferrite, and columbite.
