In the electromagnetic field computation in consideration of nonlinear magnetic anisotropy, the solution by the Newton-Raphson method has some problems which are an asymmetric matrix and poor convergence characteristic. We applied the Fixed-Point method to the electromagnetic field computation in consideration of nonlinear magnetic anisotropy and examined the usefulness of the Fixed-Point method through comparing the Fixed-Point method with the ordinary Newton-Raphson method. The Fixed-Point method with a symmetric matrix is quite faster than the Newton-Raphson method with an asymmetric matrix. Therefore, the Fixed-Point method is a very useful technique in nonlinear magnetic anisotropy problems.
