Diamagnetism occurs when the changing of an external magnetic field induces currents in the metal, causing it to repulse from the magnetic field. Since gold is both paramagnetic and diamagnetic, both cancel one another out and become weak. So a strong magnet will attract gold ever so slightly and will also repel it.
