Recently, the biological effects of electric and magnetic fields have been investigated by many researchers. In this paper, we present the visualization of magnetic field distribution under the Ultra High Voltage (UHV) power transmission lines to investigate the effects of magnetic fields on human bodies. The method for solving problems of the magnetic fields is based on the electric image method which is the best way of analyzing electric and magnetic fields around the transmission lines. The distribution of magnetic field intensities is visualized by personal computer graphics with 10 color grades. From the above, it is considered that the effects of magnetic fields on human bodies at the surface of the earth when exposed to UHV power transmission lines can be neglected.
