Abstract

The induced currents into the human body by a low-frequency magnetic field are computed using three-dimensional finite elements and a special φ-A formulation. This magnetic field is generated by a real (possibly unknown) power system. The stray field is characterized by an equivalent multipole, fitted from some local measurements of the field, which is a good compromise between accuracy and number of degrees of freedom. The methodology is validated on a test-device using the software FLUX3D.
