Magnetic imaging is an non?destructive testing (NDT) method which leads to an inverse problem if the underlying current density should be determined. The current density permits either the determination of the geometry or the conductivity of an electrical conductor. For analyzing novel electrically conductive materials, the uniformity of the conductivity is a critical characteristic. This paper presents a deconvolution based method to determine the current density distribution within an inhomogeneous electrical conductor from the resulting magnetic field measured with a state of the art GMR magnetometer.
