This paper addresses fundamental issues associated with the development of a real time inductive scanning system for non‐destructive testing of pre‐stressed and reinforced concrete. Simulated results has indicated that given a coil dimension of 300mm×300mm×2.5mm, 10mm rebars can be imaged down to a depth of 100 mm. Studies also indicate that the vertical component of the induced magnetic field is most favourable as it can be readily reconstructed to yield geometry and dimensional information pertaining to the rebar structure.
