    "abstract": "The nature of Ohm\u0027s law is examined in a turbulent flow of liquid sodium. A\nmagnetic field is applied to the flowing sodium, and the resulting magnetic\nfield is measured. The mean velocity field of the sodium is also measured in an\nidentical-scale water model of the experiment. These two fields are used to\ndetermine the terms in Ohm\u0027s law, indicating the presence of currents driven by\na turbulent electromotive force. These currents result in a diamagnetic effect,\ngenerating magnetic field in opposition to the dominant fields of the\nexperiment. The magnitude of the fluctuation-driven magnetic field is\ncomparable to that of the field induced by the sodium\u0027s mean flow.",
