Analysis of induced current density in spherical conductive model exposed simultaneously to extremely low frequency electric and magnetic fields

摘要

In this paper, the effects of electric and magnetic field components on the total induced current density in a homogeneous spherical conductive model exposed to 60 Hz electric and magnetic fields (electric field 1 kV/m, magnetic field 1 /spl mu/T) are investigated through computer analysis. The distribution profiles of the induced current density in the model exposed to extremely low frequency electric and magnetic fields in parallel with each other are almost dominated by the electric field. But the ones in the case of mutually orthogonal electric and magnetic fields are different; in other words, the total induced current densities are affected by the magnitudes and the phases of the fields.
