An analysis is given of the interaction between thermally driven currents and a large-scale magnetic field in the radiative envelope of an oblique-rotator model. The authors consider the case of a slowly decaying magnetic field, which is initially dipolar in structure. Self-consistent solutions are obtained for different values of the initial inclination of the magnetic axis with respect to the rotation axis. These calculations show that the magnetic stars are less-than-ideal bodies, having a wide spectrum of eddy-like motions that coexist with the largest scale flows in their radiative envelopes. Obviously, turbulent viscous friction plays an essential role in the dynamics of a stellar radiative zone.
