  Magnetite & Lodestone | Mineral Photos, Uses, Properties

  Magnetite as "Lodestone" Normal magnetite is attracted to a magnet, but some specimens are automagnetized and have the ability to attract small pieces of iron, small pieces of magnetite, and other magnetic objects. This form of magnetite, known as "lodestone," was man's first encounter with the property of magnetism.
