STATE AND EXPLAIN 2 MAIN POPERTIES OF A NATURAL MAGNET?
- Natural magnets are different from other magnets, because they do not need to have their properties altered in order to become magnetized.
- Natural magnets are known as permanent magnets. The continual magnetism of permanent magnets is due to the internal molecular structure of the materials.
One example of 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.
