Magnetite - Wikipedia
Magnetite is a rock mineral and one of the main iron ores with the chemical formula Fe3O4. 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. The industrial alyst is obtained from finely ground iron powder which is
