Few areas of geophysics are today progressing as rapidly as basic geomagnetism, which
seeks to understand the origin of the Earth's magnetism. Data about the present …

It is widely known that cosmic magnetic fields, ie the fields of planets, stars, and galaxies, are
produced by the hydromagnetic dynamo effect in moving electrically conducting fluids. It is …

The von Kármán Sodium (VKS) experiment studies dynamo action in the flow generated
inside a cylinder filled with liquid sodium by the rotation of coaxial impellers (the von Kármán …

A crucial point for the understanding of the von Kármán–sodium (VKS) dynamo experiment
is the influence of soft-iron impellers. We present numerical simulations of a VKS-like …

Numerical simulations of the kinematic induction equation are performed on a model
configuration of the Cadarache von-Kármán-sodium dynamo experiment. The effect of a …

We numerically investigate the efficiency of a spherical Couette flow at generating a self-
sustained magnetic field. No dynamo action occurs for axisymmetric flow, while we always …

We present hydrodynamic and magnetohydrodynamic (MHD) simulations of liquid sodium
flows in the von Kármán sodium (VKS) set-up. The counter-rotating impellers made of soft …

Since the turn of the century, experiments have produced laboratory fluid dynamos that
enable a study of the effect in controlled conditions. We review here magnetic induction …

Kinematic simulations of the induction equation are carried out for different setups suitable
for the von-Kármán-Sodium (VKS) dynamo experiment. The material properties of the flow …
