Magnetic Metal Detector or any type of magnetic detector does not even have the power to separate and discriminate metals and Gold and Silver and this is due to the magnetic field which in general has a precise classification state in the mode of diffusion or reflection for the separator or in general when the magnet is emitted it has scattered lines in the movement of its negative electric charge and it has a combination curve with the electric charge of other sources and other fields to convert and move electric charge particles and this is one of the factors that weakens the power of precise separation and discrimination in the magnet or the magnet has a continuous field current dispersion in its negative electric charge
