These devices include one or more inductor coils, which are used to collaborate with metal objects on the ground. The single coil metal detector is a basic version, which is used in a real metal detector. A metal detector consists of an oscillator that produces an alternating current. This current will pass through a coil, generating an alternating magnetic field. If an electrically conductive metal part comes close to the coil, eddy currents or eddy currents will form in the metal and this will produce a magnetic field. The other coil, which works as a magnetometer, is used to evaluate the magnetic field, the alteration in the magnetic field can be detected due to the metal object. All metal detectors are designed to detect a variety of metals which include silver, gold, iron, copper, nickel, brass, tin, aluminum, bronze and lead. They do not detect non-metallic objects, such as diamonds, precious stones, pearls, paper, bones or stone figures. A metal detector has the ability to spot the disparity between different types of metals or
