How Metal Detectors Find Gold With Gold Detector
2021.8.9 The working principle of a gold detector is that it transmits electromagnetic fields into the ground. It then processes the signal that is coming off that field based on how it reacts to pieces of metal that are buried beneath the ground. The electromagnetic field is produced using an electrical current from a power source.

Metal detectors work by transmitting an electromagnetic field from the search coil into the ground. Any metal objects (targets) within the electromagnetic field will become energised and retransmit an electromagnetic field of their own. The detector’s search coil receives the retransmitted field and alerts the user by producing a target response.
