METAL DETECTOR
Metal detector is an electronic instrument. Which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects.
The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field. If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces a magnetic field of its own.
