Magnetic minerals are naturally occurring substances that exhibit magnetic properties. These minerals, such as magnetite and hematite, can attract or repel other magnetic materials. They are commonly found in igneous and metamorphic rocks and play a significant role in geology and earth sciences. These minerals are essential for various applications, including geophysical surveys and mineral exploration. Their magnetic properties help scientists understand the Earth's magnetic field and its history. Additionally, magnetic minerals are used in technology, such as in the production of permanent magnets and magnetic storage devices.
