Electric and magnetic fields seem to extend their influences beyond the Physical Plane. This may explain why they have effects, both beneficial and detrimental, on the bodies of all living creatures. In fact all life forms generate and use these fields in the electrochemistry of their normal functioning.
Movement of these fields give rise to frequencies each of which has unique effects, such as colour, heat, light, radio waves.
