· Electromagnetic Induction: The core of a metal detector is a coil of wire that has an electric current. When this current flows through the coil, it generates a magnetic field around it. This magnetic field is crucial for the detection process. When the coil passes over a metal object, the magnetic field renders an electric current in the metal.

· Metal detectors work on the principle of electromagnetic induction. When a metal object is brought near the coil of the detector, it produces an electric current. This current creates a magnetic field around the coil, which in turn generates a signal. The detector then amplifies this signal and alerts the user with a beep or a flashing light.

· 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

· At its core, a metal detector is a device that uses electromagnetic fields to detect the presence of metallic objects. It consists of three main components: a control box, a search coil, and a shaft that connects the two. The control box is essentially the brain of the metal detector, housing the circuitry and controls.
