magnetite
Magnetite, a ferrimagnetic mineral with chemical formula Fe3O4, one of several iron oxides, is one of the more common meteor-wrongs. Magnetite displays a black exterior and magnetic properties.
magnetite
Magnetite can be a found in a meteorite's crust. When a meteor enters the earth's atmosphere the rock's surface is ablated by ultra high temperatures. Before it hits the ground, the molten surface solidifies into a thin glassy coating, called fusion crust. Crystals of magnetite color the thin fusion crust black. (Magnetite streaks black)
lodestone
A piece of intensely magnetic magnetite was used as an early form of magnetic compass. Iron, steel and ordinary magnetite are attracted to a magnetic field, including the Earth's magnetic field. Only magnetite with a particular crystalline structure, lodestone, can act as a natural magnet and attract and magnetize iron. The name "magnet" comes from lodestones found in a place called Magnesia.
