    "abstract": "We report the observation of dynamo action in the VKS experiment, i.e., the\ngeneration of magnetic field by a strongly turbulent swirling flow of liquid\nsodium. Both mean and fluctuating parts of the field are studied. The dynamo\nthreshold corresponds to a magnetic Reynolds number Rm \\sim 30. A mean magnetic\nfield of order 40 G is observed 30% above threshold at the flow lateral\nboundary. The rms fluctuations are larger than the corresponding mean value for\ntwo of the components. The scaling of the mean square magnetic field is\ncompared to a prediction previously made for high Reynolds number flows.",
