Magnetic minerals are naturally occurring substances that can be magnetized or attracted to magnets. They contain iron or other magnetic elements, which give them their unique properties. Common examples include magnetite, hematite, and pyrrhotite. These minerals are often found in igneous and sedimentary rocks and play a significant role in geology and earth sciences. The study of magnetic minerals helps scientists understand the Earth's magnetic field and its history. They are also important in various applications, such as geophysical surveys and mineral exploration. By analyzing these minerals, researchers can gain insights into past geological events and the movement of tectonic plates.
