  The possibility of the existence of quasi-stationary electromagnetic fields
in plasma supported by their own self-consistent current follows from Maxwell's
equations with field sources. These equations also give rise to a wave equation
for the density of a self-consistent current and a nonlinear kinematic equation
for the velocity of electric charges, from which follows the possibility of
excitation of a "magnetic dynamo" and localized rotating plasma structures
having a magnetic field. An analytical boundary condition for the excitation or
attenuation of turbulence and "magnetic dynamo" is obtained.
