This paper addresses the issue of the interaction of the human body with power frequency (50/60 Hz) magnetic fields. Two human body models are used; a simple spheroid based on an analytical method and an approximate human shape based on finite element method (FEM). The employed human body models are positioned in two magnetic field sources; under a power transmission line and inside an electric power substation representing typical exposure cases. The magnetically induced currents inside human body due to the exposure to power frequency magnetic fields are evaluated. A number of parameters such as human dimensions and proximity to the current-carrying conductors are considered. A comparative analysis of the magnetic induction inside the human body due to the different human models and magnetic field sources is also presented.
