MagnetiteWikipedia
Magnetite is a 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 of
