At the security area, people walk through a large coil of wire and through a weak AC magnetic field. What is the result of a small piece of metal on a person that slightly alters the magnetic field in the coil?A. Temperature differences are induced in the metal that can be detected by the coil of wire, this in turn changes the AC current in the coils and sets off an alarm. B. Radiation is induced in the metal that can be detected by the coil of wire, this in turn changes the AC current in the coils and sets off an alarm. C. Electric currents are induced in the metal that changes the magnetic field, this in turn changes the AC current in the coils and sets off an alarm.
