Magnets are commonly used as a preliminary stage when testing gold. If the piece is strongly attracted to the magnet, then it is not gold. If it is slightly attracted it may not be pure gold because gold has no magnetic properties. In this case, you would proceed to the acid or electronic gold test. This very powerful, rare earth magnet is most preferred above all other magnets among gold buyers.
