ABSTRACT:
A system and method for determining the location of a remote object connected to an induction coil using a magnetic tracking sensor. The system and method include locating a magnetic core asymmetrically disposed within the induction coil located near the remote object, and operably connecting a single DC electrical circuit o ends defining the induction coil. The DC electrical circuit provides a DC current to the induction coil while the induction coil is disposed in an external AC magnetic field. The DC current adjusts the level of saturation of the magnetic core, and hence varies a response signal of the induction coil disposed in the external AC magnetic field to provide magnetic tracking of the induction coil.
