Magnetic induction tomography is an emerging tomographic technique that can map the passive electromagnetic properties of an object non-invasively. Thus it has wide applications to non-destructive evaluations (NDE). Previously in our group, we developed an eight-channel MIT system and proposed it as a novel non-destructive inspection tool for metallic pipes, a new application for MIT. This study is focused on the validation of the forward model. A mathematical model is prepared based on the laboratory prototype system. The induced voltages are simulated according to different profiles of damaged pipes. The voltages are then compared with those collected from experimental data. The evaluations reveal the capability and detectability of the MIT system for pipeline inspection.
