What is a magnetite stone?
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe3O4. 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.
What is magnetite crystal used for?
Magnetite is often used in jewelry due to its supposed magnetic healing properties. Magnetite is a rock mineral and, along with hematite, is mined as one of the main iron ores.

Why does the mineral magnetite stick to a magnet?
First The first magnets were pieces of a naturally occurring magnetic mineral called magnetite. All magnetite sticks to magnets because it contains a lot of iron. The black rock in your set of test objects is magnetite. When magnetite is magnetic by itself, it is called lodestone.
How is magnetite used commercially?
Magnetite is sometimes used as an additive to fertilizer, providing iron as a micronutrient. Providing the pigment in some paints and toners is another of the uses of magnetite. It is especially common in the toner used in the photocopying process.
