A metal detector is an electronic device used to find hidden or buried metallic objects. How It Works • Electromagnetic Field: The device uses a search coil to send an electromagnetic field into the ground, water, or air. • Eddy Currents: When the field hits a metal object, it creates tiny electric currents (called eddy currents) inside that object. • Alert Signal: The metal object generates its own small magnetic field, which the detector senses and turns into an audio tone, beep, light, or digital screen reading
