 Where is magnet found in nature?

Magnetite (Fe3O4) is the most common natural magnetic mineral found on Earth. It can be found in igneous, metamorphic, and sedimentary rocks. Other minerals that are also magnetic include pyrrhotite, franklinite, and magnetite in beach sand. Some minerals such as hematite (Fe2O3) and lodestone have natural weak magnetism. Additionally, certain types of rocks, such as basalt and other igneous rocks, can become magnetized through a process called "thermal remagnetization". These magnets can be found in many locations all over the world, but they are especially abundant in volcanic and mountainous regions.
