Notes:
Stationary large-scale magnetic fields generated by an electrically conducting fluid in a spherical region are examined analytically, using the concept of the turbulent dynamo based on helicity and cross-helicity effects. Under this concept, the toroidal magnetic field is induced through the combination of a rotational motion and the turbulent cross-helicity effect. This field generates the poloidal one through the turbulent residual-helicity (alpha) effect. A new magnetic-field generation mechanism in the vicinity of the poles is also described. These findings are discussed in the context of the dimension of the convection part of a stellar object. © 1996 American Institute of Physics.
