【Abstract】 A series solution of eddy current expressed by analytical method is given for eddy current problems of rectangular lamina under the transverse magnetic field which varies with harmony. As compared with the variational method, the results indicate that the method in this paper not only improves the numerically computational precision, but reduces the computational memory and time. The simple and effective method is provided for the calculation of eddy current in the project.更多还原
