Walk-through metal detector working principle
Modern walk-through metal detectors use PI, or pulse induction technology. PI systems send out short and powerful bursts of currents through a coil of wire and each pulse generates a short magnetic field. When a metallic object enters the magnetic field, a reflective magnetic field is then created and picked up by the receiver coil.
