ABSTRACT:
A magnetic identification system marker is adapted to generate magnetic fields at frequencies that (1) are harmonically related to an incident magnetic field applied within an interrogation zone and (2) have both even and odd harmonics of the incident field frequency that provide the marker with signal identity, and coding capability. The marker is an elongated, ductile strip of amorphous ferromagnetic material.
