Magnetite
Know More

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4It 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 ....
