Synthesis of Magnetite (or Lodestone) Background Magnetite is an oxide of iron that has been known for thousands of years. Magnetite (Fe 3 O 4) is thought to have been named after Magnesia, in Asia Minor. The importance of magnetite in history is due not only to its use as a source of iron, but also to it's magnetic properties.
