We have already analyzed a flux concentration apparatus with two conducting plates by using a newly developed iterative 3-D calculation method.[1] [2] An improved formulation is also treated in this paper. This calculation method is applied to the present four-plate type model, to prove its adaptability and to search for more efficient design of such apparatus. Distributions of flux densities, eddy currents and scalar potentials are calculated and discussed. The role of the scalar potential for the 3-D eddy current diffusion problems is also interpreted, based on our calculation results.}, pages = {126--129}, title = {Four components three dimensional FEM analysis of flux concentration apparatus with four plate}, volume = {24}, year = {1988} }
