Vedclass · Answer

(C) metal detector consists of a coil that generates a time-varying magnetic field. When a metallic object is brought near the coil,the changing magnetic field induces eddy currents in the metal object. These eddy currents create their own magnetic field,which is detected by the device. This process is based on the principle of electromagnetic induction.
