|b Many of the astrophysical bodies have their magnetic field which is generated by electric conductivity of the core. The generation of magnetic field in a homogeneous electrical field is normally a threshold process, some of these fields are axisymmetric such as the field of the Earth, Jupiter and Saturn and some of them have a non-axisymmetric magnetic field like the field of the Sun, moreover others have the non-axisymmetric dominates over the axisymmetric field as in Uranus and Neptune Stachenko (1993). With these observations on mind we investigate excitable conditions of axisymmetric and non-axisymmetric field mode in spherical mean-field dynamo. In this paper, we consider the mixed; axisymmetric and non-axisymmetric on a spherical mean-field α2 dynamo model through nonlinear calculations with α-quenching feedback. It seems to be that the axisymmetric solution is more excited than the non-axisymmetric one in his model, the generated field could be an axisymmetric, nonaxisymmetric or both.
