Diamagnetism of Gold. Generally, pure gold is not magnetic. This is established by Faraday's Law of Magnetic Induction. When a material or element is placed in a magnetic field, it will react to the magnetic forces in different ways. Some elements, such as iron and cobalt, are highly susceptible to these fields, which will attract them closer.
