Models of middle main-sequence magnetic stars with a convective core in which a dynamically consistent alpha-omega-effect dynamo generates the field are constructed, and are compared to fossil field/oblique rotator models. First the radiation envelope is assumed to be in strict equilibrium with no meridional circulation, then models with a thermally driven meridional circulation in the envelope consistent with the MHD equation are considered. The magnetic field has dipolar angular form, and an axis aligned with the rotation axis. Solutions for slow rotation and small internal flux could not be found using these models, which was also the case for the directly analogous fossil models. The ratio of interior to surface fields is somewhat less in these core-dynamo models than in fossil models, increasing as (Lambdaomega/lambda sub H) to the one-third power for zero envelope circulation, instead of to the one-half power using the fossil model.
