Magnetic stimulation applied on a non-homogeneous volume as a rough simulation of a human body structure. Several coil contours L_i with excitation currents I_i are positioned in the air (γ_o and μ_o are the air specific conductivity and magnetic permeability) on the upper surface of the volume. The structure consists of various layers and zones Ω_m of different conductivities γ_m and magnetic permeabilities μ_m.
