WebSo what is a magnetic mineral doing inside our brains? Caltech geobiologist Joseph Kirschvink thinks he might have the answer: Magnetite allows us to sense Earth's magnetic field. This remarkable ability is present all across the animal kingdom, from bacteria and birds to turtles and bats. WebMagnetite is seen as a metallic to dull luster, black in color, and its streak is black. It is also a mineral and one of the two main oxides of iron ore, with the chemical formula Fe3O4. Magnetite’s greatest use is being an important iron ore in steel manufacturing.
