What is it about?

Results from non linear MHD dynamo experiments with a three-dimensional steady and smooth flow that drives fast dynamo action. This dynamo has a high growth rate in the linear regime, and that it can saturate at a level significantly higher than intermittent turbulent dynamos, namely at energy equipartition.

Why is it important?

Strong magnetic fields, in near equipartition, can be generated also by a non-turbulent dynamo. A striking result is that the saturation state of this dynamo reveals interesting transitions between turbulent and laminar states.
