Figure 4From: Effect of Contour Shape of Nervous System Electromagnetic Stimulation Coils on the Induced Electrical Field DistributionThe electrical field distribution E(x) for sets of three coils, each set using four types of coil contours. Two of the coils are positioned in the XOY plane and one on the YOZ plane, symmetrically oriented with respect to the negative Z axis. Thus the region to be stimulated is the positive half-space defined by XOY and the positive Z-axis.Back to article page
