The study produces a coupled system of equations known as Maxwell's equations, which are nonlinear differential equations representing electromagnetic fields. The results of the work are expected to be of fundamental interest for Applied Mathematicians, Physicists, and manufacturing engineers. This model could be immediately used for testing and design of electric machines, transmission lines, and cables. The particular case to be studied under the proposal is look for tubular conductor models that might not be aligned i.e. the central axes are parallel to each other but the centers are not co-axial. This type of arrangement may cause different distributions or non-uniform distribution of electromagnetic field vectors. Thus in turn may generate extra heat losses. The purpose of the present talk/work is to look for losses of power and hence design a model, which may perform as good as in case of co-axial winding with at least not more losses than co-axial case. In general can not have ideal case of no losses.) References: 1. A. Krawczyk & J.A. Tegopoulos: Numerical modeling of Eddy Currents, Oxford Univ. press, 1993. 2. K. Singh-Altmayer.
