Magnetite - Wikipedia Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4 It is one of the oxides of iron, and is ferrimagnetic; [6] it is attracted to a magnet and can be magnetized to become a permanent magnet itself [7][8] With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth [7][9] Naturally
Magnetite | Common Minerals In Our Earth: The Geologic Importance of Magnetite Magnetite is one of the most widespread iron oxide minerals and occurs in a variety of geologic environments It is a common accessory mineral in igneous rocks, but seldom forms crystals large enough to be seen in hand samples More often, magnetite is dispersed throughout a rock as microscopic crystals that form along the edges of iron

Magnetic Properties, Iron Oxide, Magnetism - Britannica Magnetite, iron oxide mineral (FeFe2O4, or Fe3O4) that is the chief member of one of the series of the spinel (q v ) group Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites,
Magnetite: The mineral Magnetite information and pictures Magnetite is best known for its property of being strongly attracted to magnet s Some forms of Magnetite from specific localities are in fact themselves magnets Commonly known as Lodestone, this magnetic form of Magnetite is the only mineral that is a natural magnet Due to the magnetism of Lodestone, small iron particles are often found clinging to its surfaces (Some dealers may even
