  Initially, we present our original fast dynamo mechanism being potentially at
work concerning the Sun and the solar type stars. Then, based on this new
prototype model, a dynamo action model explaining the generation of the
magnetic fields for A, Ap and Am type stars will be derived. We argue that
their magnetic behavior is essentially due to locally exotic plasma properties
leading to large scale charge separation in their interior. Their powerful
magnetic fields are generated by the revolution speed of these excess positive
or negative charges tightly associated with the formation of one or two so
called Torus structures. The lifespan of the Torus charge defines the stellar
activity cycle. In the solar case, two Torus structures are formed preserving
their charge for 11 years. The Torus charging results from two processes:
First, the stellar differential rotation with its shear layers and second, the
local plasma property that the plasma rotational speed (U) is equal or greater
than the local light speed (v) in the medium. If U is greater than v, then two
nearby pocket charges (initially formed by the stellar differential rotation)
will be mutually attracted. That is, the attractive magnetic force will be
greater than the repulsive electric one. In addition, the same poloidal field,
in the subphotosphere shear layer, produces an excess charge generating the
starspot activity. The solar birthplace of Torus, within the tachocline, is
positioned at 45 deg. latitudes. Each Torus drifts equatorward increasing
steadily its own rotational speed and, consequently, its own strength of
poloidal magnetic field. A single Torus, over the equatorial plane, is probably
formed in the interior of an Ap type star producing its strong and global
dipole like magnetic field.
