  A sensitivity profile of a planar spiral coil sensor (PSCS) is proposed and
is used to generate the relation of 3-D position of object observed using three
PSCSs, one in each x, y, and z axis to the sensors response. A numerical
procedure using self consistent field-like method to reconstruct the real
position of observed object from sensor sensitivity is presented and the
results are discussed. Unfortunately, the procedure fails to approach the
desired results due to the existence of quadratic terms.
