ABSTRACT:
A metal detector is proposed, in which field coils and receiving coils are arranged on either side of a zone to be monitored. In order to bring about a more uniform sensitivity distribution within the zone to be monitored, alternately the field coil on one side and the field coil on the other side is excited for radiating a magnetic field.
