Abstract
A three-dimensional self-organization process in an incompressible dissipative plasma is investigated by means of a magnetohydrodynamic simulation. Two typical phases are observed, i.e., the energy-relaxation phase and the inverse-cascade phase. In the relaxation phase the total magnetic energy rapidly decreases while the magnetic structure is transformed into a simpler one by magnetic reconnection. In the inverse-cascade phase the magnetic helicity spectrum shifts towards the low-wave-number region while the magnetic energy spectrum shifts towards the high-wave-number region.Keywords
