Magnetic Susceptibility Imaging as a New Approach towards Characterization and Testing of Para-and Diamagnetic Materials

Abstract : All materials interact with a magnetic field to some extent. This interaction is generally quantified by the magnetic susceptibility . Non-ferromagnetic materials' group comprises (besides many others) all kinds of plastics, glass, carbon and non-ferrous metals. It is legitimate to assume that there is a correlation between local  value and local anomalies of material composition, deformation and stress, which makes it interesting to explore related sensor principles with a potential for NDT application. This contribution however concerns a novel magnetic force based sensor for laterally resolved susceptibility measurement and demonstrates the possible range of NDT applications on different non-ferromagnetic material samples.
