Black Iron Oxide ( Magnetite )
About Black Iron Oxide ( Magnetite )
Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4.
It is ferrimagnetic, 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 iron, which is how ancient peoples first discovered the property of magnetism.
Small grains of magnetite occur in almost all igneous and metamorphic rocks.
Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak.
