Magnetite is a mineral and a naturally occurring magnetic material made up of iron oxide (Fe3O4). It is commonly found in a variety of geological settings, including igneous and metamorphic rocks, as well as in sedimentary deposits such as banded iron formations. Magnetite is known for its strong magnetic properties, which make it useful in a variety of applications including in the production of magnetic recording media, in magnetic separation processes, and in the development of magnetic nanoparticles for medical and environmental applications. Research on magnetite focuses on understanding its structure, properties, and potential applications in various fields.
