When this field is near a conductive material, the field creates (induces) small electrical eddy-currents in the material. These currents generate a magnetic field that opposes the field from the sensor . As the gap between the probe and target gets smaller, the field interaction changes. The sensor electronics measure this field interaction and generate an output voltage proportional to the change in the gap. Conductive TargetsThe eddy-currents induced in the target material are dependent on the material s properties of permeability and resistivity.
