This paper deals with the electromagnetic field energy flux in the basic electric components and engines by the means of Maxwell’s theory of the electromagnetic field. The ideas of this process are often incorrect because basic electric components and engines is uncommon studied and it paid only minimal attention. However, the knowledge of this process is very important for precisely understanding of its operation. The shell transformer, as one of the often used electric engine, was selected to illustrate the application of this theory on the computing the electromagnetic field energy flux. At the first, electric intensity E(t) and magnetic intensity H(t) of the electromagnetic field in the transformer core and in its winding was expressed. At the second, the density of the transmitted electromagnetic field energy per unit time i.e. the density of power, known as Poynting’s vector, was calculated for the transformer winding as well as its core. Next, the transmitted electromagnetic field energy per unit time, i.e. the transmitted power was calculated for once again for the transformer core and for its winding too. So in this work was demonstrated how the energy spread actually in one of the electric engine ? in the transformer.
