Electromagnetic field (EMF) radiated emissions from Extremely Low Frequency (ELF) source power transmission line can produce interference on electric components at vehicle traveling at variable speed. The passenger vehicle may also have EMF problem health impact, which has been categorized as a new form of pollution as air and water pollution. This situation has been largely ignored by the industry, but it is hoped that this work will open up discussion and finding formulation capable to be designed to manufacture a new device for measuring the EMF at variable speed. In this paper, an artificial neural network (ANN) is developed to estimate the EMF. A set of near field measurements outside the vehicle were used to train ANN. Estimations of the EMF ELF for various distances from the a high tension power line are presented.
