    "abstract": "The magnetic field measured in the Madison Dynamo Experiment shows\nintermittent periods of growth when an axial magnetic field is applied. The\ngeometry of the intermittent field is consistent with the fastest growing\nmagnetic eigenmode predicted by kinematic dynamo theory using a laminar model\nof the mean flow. Though the eigenmodes of the mean flow are decaying, it is\npostulated that turbulent fluctuations of the velocity field change the flow\ngeometry such that the eigenmode growth rate is temporarily positive.\nTherefore, it is expected that a characteristic of the onset of a turbulent\ndynamo is magnetic intermittency.",
