Abstract:
A thought analysis on the self-organization theories of dissipative MHD plasmas is presented to lead to three groups of theories that lead to the same relaxed state of nabla x B = lambda B, in order to find an essential physical picture embedded in the self-organization phenomena due to nonlinear and dissipative processes. The self-organized relaxed state due to the dissipation by the Ohm loss is shown to be formulated generally as the atate such that yields the minimum dissipation rate of global auto-and /or cross-correlations between two quantities in j, B, and A for their own instantaneous values of the global correlations.
