About Magnetite
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.
