    "abstract": "We are investigating numerically the non-linear behavior of a space-periodic\nMHD system with ABC forcing. Most computations are performed for magnetic\nReynolds numbers increasing from 0 to 60 and a fixed kinematic Reynolds number,\nsmall enough for the trivial solution with a zero magnetic field to be stable\nto velocity perturbations. At the critical magnetic Reynolds number for the\nonset of instability of the trivial solution the dominant eigenvalue of the\nkinematic dynamo problem is real. In agreement with the bifurcation theory new\nsteady states with non-vanishing magnetic field appear in this bifurcation.\nSubsequent bifurcations are investigated. A regime is detected, where chaotic\nvariations of the magnetic field orientation (analogous to magnetic field\nreversals) are observed in the temporal evolution of the system.",
