  The effect of magnetic turbulence in shaping the current density in
axisymmetric magnetized plasma is analyzed using a turbulent extension of Ohm's
law derived from the self-consistent action-angle transport theory. Besides the
well-known hyper-resistive (helicity-conserving) contribution, the generalized
Ohm's law contains an anomalous resistivity term, and a turbulent
bootstrap-like term proportional to the current density derivative. The
numerical solution of the equation for equilibrium and turbulence profiles
characteristic of conventional and advanced scenarios shows that, trough
"turbulent bootstrap" effect and anomalous resistivity turbulence can generate
power and parallel current which are a sizable portion (about 20-25%) of the
corresponding effects associated with the neoclassical bootstrap effect. The
degree of alignment of the turbulence peak and the pressure gradient plays an
important role in defining the steady-state regime. In fully bootstrapped
tokamak, the hyper-resistivity is essential in overcoming the intrinsic
limitation of the hollow current profile.
