A sensing system includes a conductor with a current flow path therethrough. A first location of the conductor defines a first cross-sectional area and a second location defines a second cross-sectional area, wherein a current flowing through the conductor establishes magnetic field lines having strengths that vary according the conductor cross-sectional area. A plurality of sensors include a first and second sensors situated proximate the first and second locations, respectively, and configured to measure the magnetic field lines at their respective locations.
