Description
It is shown by three-dimensional magnetohydrodynamic simulations that the toroidal current Jz can be induced by a process of relaxation without helicity invariance under a condition of no external magnetic helicity injection.It is shown that the magnetic helicity is induced during relaxation and it ispassively determined as a result of the time evolution of the dynamicalsystem. Numerical results suggest thatthe basic process for the toroidal current drive duringrelaxation is the nonlinear energy transfer fromthe toroidal to the poloidal magnetic energy with the intervention of the kinetic energy.It is demonstrated that self-organization to the lower eigenmode with a larger-scale structureoccurs during relaxation.
