| Research Abstract |
Wavelet function based analysis of the mechanism of magnetic field generation in a fully developed magnetohydrodynamic turbulence of space or fusion plasmas was carried out. In the present study we focused on the dynamics of the Hall magnetohydrodynamic system. Energy transfers by the quadratic terms effects are analyzed by direct numerical simulation. We found that slow compensating energy transfer after the formation of self-similar, universal turbulent state.
