Abstract

Apparatus for distinguishing two different metallic objects, such as coin pieces, characterized in that it comprises an electromagnetic device containing two coils formed by winding together two separate conductors, one source of alternating current with the terminals of which one of the coils is connected, so that an alternating magnetic field is created by the excitation of said coil by the source of alternating current and produces by induction a voltage in the other coil, means that allow to install a metallic object that must be explored in the alternating magnetic field, and connected means with the terminals of the other coil to establish a distinction between the induced voltage and an induced voltage in the other coil, when a reference metallic object is placed in the alternating magnetic field.
