Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral, and not only because it is magnetic.The formula could be written as Fe 2+ Fe 3+ 2O 4, which more precisely designates one of its peculiarities.It contains both ferrous Fe 2+ and ferric Fe 3+ ions implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

MagnetiteWikipedia

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 naturallyoccurring minerals on Earth. Naturallymagnetized pieces of magnetite, called lodestone, will attract small pieces
