  • Magnetite - Wikipedia

    Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...

    EtymologyCharacteristicsChemistryPropertiesDistributionSignificanceResourcesSourcesMagnetite is an iron oxide with the chemical formula Fe3O4. Actually, it is a mixture of two iron oxides, FeO and Fe2O3. Therefore, we can show it as FeOFe2O3. According to the IUPAC nomenclature, its name is iron (II, III) oxide. But, commonly we name this as ferrous-ferric oxide. Magnetite got its name because it is a magnet.
