Question

what is natural magnet made of

Answer 1

I think the natural magnets are made up of ferromagnetic metals

Answer 2

a natural magnet is the mineral magnetite, composed of an iron oxide. A lodestone is a type of magnetite that was one of the earliest natural magnets discovered. Basalt, which forms when lava hardens, also contains magnetite, although its magnetic field is weak.

Another natural magnet is pyrrhotite, which is formed of iron sulfide. It is only weakly magnetic, with the strength of its field varying according to the amount of iron contained.

The Earth itself behaves as a natural magnet. It has a magnetic south pole which is actually located geographically north, in Canada. Likewise, its magnetic north pole is actually geographically south, in the Antarctic.
