| Abstract: | The coupling conditions between eddy current region and free space in 3-D eddy current problems are derived in potential A-V with the Coulomb's gauge.Based on these conditions, a new FE-BE analysis method is proposed.This new method has been used to compute the model B of TEAM workshop problem 21.The computed results of the normal component magnetic flux density near the surface of the steel plate approach to the measured results.The distribution of eddy currents in the steel plate is reasonable. |
