    For example, when iron exists as a solid pure metal or metal alloy, as it does in a paper clip or an iron meteorite, it is ferromagnetic. But when iron exists in the form of charged atomic particles called ions that are dispersed in solid solution throughout the chemistry of a gemstone, it is generally paramagnetic.

  • Paramagnetism

    Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the direction opposite to that of the applied magnetic field.
