    "abstract": "An axisymmetric magnetic field is applied to a spherical, turbulent flow of\nliquid sodium. An induced magnetic dipole moment is measured which cannot be\ngenerated by the interaction of the axisymmetric mean flow with the applied\nfield, indicating the presence of a turbulent electromotive force. It is shown\nthat the induced dipole moment should vanish for any axisymmetric laminar flow.\nAlso observed is the production of toroidal magnetic field from applied\npoloidal magnetic field (the omega-effect). Its potential role in the\nproduction of the induced dipole is discussed.",
