Recent spectro-polarimetric observations of magnetic fields in solar-like stars have shown that strong toroidal fields must be generated axisymmetrically.

This is an important challenge for dynamo theory. In this talk a new class of  mean field dynamo models with a consistent coupling between the interior and a coronal model is presented. Observational consequences for the findings of See et al. (2016) are then discussed. The possibility that a dynamo generated field hosts a force-free corona is also discussed.
