Abstract :
It is of great significance for theory research and engineering application of electromagnetic device to digitize the magnetic curve of ferromagnetic material. A new method, which combines cubic spline interpolation and least square fitting in different interval, is presented in this paper. The simulation results suggest that the fitting relative error don´t exceed 0.38%, and that the proposed method be well worth to popularize and apply.
