This paper suggests a new method for determing theinitial condittons of networks with degenerate cut-sets,which is strictlybased on the physical relationship between currents and magnetic fieldcorresponding witth them.This method first sets up a reasonable magne-tic network for solution,and then finds out the transfer linkages byexciting sources in this network,so that the initial conditions can befinally determined.Consequently,this method is simple,normalizable,having clear and correct physical concept,and advantageous to solvingcomplex networks.
