Magnetic Induction Tomography (MIT) belongs to the noncontact electromagnetic imaging techniques. This paper focuses on determination of a secondary magnetic field map calculated with the help of the Biot-Savart law around the low-conductivity object. The inclusions of various shapes and different electrical conductivities values and two measurement planes are considered. In each case the objects’...
A goal function scan based on an extended area approach is applied to determine size and depth of a defect in Lorentz force evaluation (LFE). Four datasets of a laminated aluminium specimen with a cylindrical defect at depths of 2, 4, 8 and 14 mm are simulated with the finite element method. LFE yields the correct defect sizes and depths for all four defects with a root mean square error of 0.95,...
