Novel method of calculation of eddy-current losses induced by a.c. flowing through conductors

A method of calculation of the eddy-current losses which are produced within a conducting solid by a.c. flowing through cylindrical or ribbon conductors is presented. The eddy-current losses are expressed in terms of the mutual and external resistances of the conductors in presence of the solid. The method presented permits the computation of eddy-current losses withoutintegrating the Poynting vector.
