  This work tackles a significant challenge in dynamo theory: the possibility
of long-term amplification and maintenance of an axisymmetric magnetic field.
We introduce a novel model that allows for non-trivial axially-symmetric
steady-state solutions for the magnetic field, particularly when the dynamo
operates primarily within a "nearly-spherical" toroidal volume inside a fluid
shell surrounding a solid core. In this model, Ohm's law is generalized to
include the restoring friction force, which aligns the velocity of the shell
with the rotational speed of the inner core and outer mantle. Our findings
reveal that, in this context, Cowling's theorem and the neutral point argument
are modified, leading to magnetic energy growth for a suitable choice of
toroidal flow. The global equilibrium magnetic field that emerges from our
model exhibits a dipolar character.
