When metaldetector metal is in their vicinity, a signal is detected owing to eddy currents induced inside the metal. What authorized detectors to discriminate between metals was the fact that each and every metal has a unique section reaction when subjected to alternating current; lengthier waves (very low frequency) penetrate floor further, and choose for top-conductivity targets like silver, and copper; than shorter waves (bigger frequency) which, while much less ground penetrating, choose for reduced-conductivity targets like iron.
