Cosmic magnetic fields, including the fields of planets, stars, and galaxies, are believed to
be caused by dynamo action in moving electrically conducting fluids. While the theory and …

Magnetic field generation and evolution in celestial bodies—the subject matter of the theory
of the dynamo—held Ya B Zeldovich's interest for years. Over the time since then, the study …

We report the observation of dynamo action in the von Kármán sodium experiment, ie, the
generation of a magnetic field by a strongly turbulent swirling flow of liquid sodium. Both …

Magnetism is one of the most pervasive features of the Universe, with planets, stars and
entire galaxies all having associated magnetic fields. All of these fields are generated by the …

We report the first experimental observation of reversals of a dynamo field generated in a
laboratory experiment based on a turbulent flow of liquid sodium. The magnetic field …

Magnetic fields are ubiquitous in the Universe. The energy density of these fields is typically
comparable to the energy density of the fluid motions of the plasma in which they are …

There has been a revolution in understanding the nature of the Sun's atmosphere that has
been stimulated by high-resolution satellite observations together with the realisation that …

The magnetic field of the Earth is by far the best documented magnetic field of all known
planets. Considerable progress has been made in our understanding of its characteristics …

Although the origin of Earth's and other celestial bodies' magnetic fields remains unknown,
we do know that the motion of electrically conducting fluids generates and maintains these …

We analyze the initial, kinematic stage of magnetic field evolution in an isotropic and
homogeneous turbulent conducting fluid with a rough velocity field, v (l)∼ l α, α< 1. This …
