Regarding the possibility of biological effects caused by exposure to ELF (extremely low frequency) magnetic fields, magnetically induced current inside the human body has been a focus of research. To clarify the induced current characteristics inside the human body, we developed estimation tools. One was a numerical calculation code and the other was a human model. The numerical calculation code was based on a surface charge method. The human model was composed of several organs and other parts of the human body, whose shapes were spheroids or cylinders. Organs taken into account were the brain, heart, lungs, liver and intestines. The validity of the calculation code was shown by comparing it with an analytical solution using a homogeneous spheroid model. The discrepancy was within 6.5%. The applicability of the code to the human body were shown. In addition, by applying the calculation code to the human model, effects of the organ conductivity difference to the induced current distribution were estimated. As a result, the value of organ conductivity very much affected the induced current distribution inside the human body.
