Electrical impedance tomography, which visualizes the impedance distribution in a living body, is a new method for capturing tomographic images of living organisms. This has the advantages of non-exposure, small size, continuous/long time measurement. However, it is necessary to attach the electrode, and it is strongly affected by the attachment condition. On the other hand, current induced magnetic tomography (CIMT) was devised to use magnetic force to obtain impedance distribution without electrical contact. In this paper, a CIMT system was built using a current of 766.6Hz as a proof of principle. In addition, we show that the CIMT system can be used to magnetically visualize the impedance distribution.
