| 摘 要： | A new dynamo model based on the polarization of plasma is presented in this paper. From the Maxwell equations in a moving medium, a magnetization vector can be caused with Rongon current. The steady solar magnetic field is solved from the equations. On the assumption that the meridianal flow is ignored, the distribution of magnetic field is put out. In the model, there is no additional parameter considered. The intensity of magnetic field inside the sun ranges from 1-6 T. The surface magnetic field around the pole is in the order of 1 ×10-3 T, at low latitude the calculated surface magnetic field has the order of 1×10-2 T. The maximum magnetic field is around 30° in latitude.
