Shielding in magnetic field is more difficult than in electric field. So, it can be said that magnetic field influences the bio-compatibility more than electric field. In order to prevent distortions in the image or magnetic field by the micro-pin after permanent transplant of an anastomotic ring during free flap or plastic reconstruction, the current density, magnetic susceptibility, and electrical conductivity of Ti-6Al-4V must be evaluated. The result of Finite Element Model (FEM) can be highly trusted when it contains finite plane as in electrical instruments. However, the evaluative analysis is rather vague for magnetic fields, thus limits 3-dimensional region segmentation. Consequently, it is more accurate to apply Biot-Savart"s law if there is no dielectric substance. In this study, human tissue model was hypothesized to be a magnetic cube cell, modeled through Impedance Network, and analyzed after converting the Maxwell equation to Circuit equation. Impedance method is highly effect for finding the inner current density or induced electric field if the frequency is low. When human tissue is exposed to a time-variant magnetic field, the human body becomes non-assimilative, hence, a critical factor that could influence the magnetic field. The eddy current can be calculated by forming an electrical network from the complex conductivity of the tissue.
