Earth's magnetic field is generated by fluid motions in the outer core. This geodynamo has
operated for over 3.4 billion years. However, the mechanism that has sustained the …

The magnetic fields of the planets, including the Earth, are generated by dynamo action in
their fluid cores. Numerical models of this process have been developed that solve the …

Exchange theories posit that trust has an important and favorable influence on dyadic
interactions. This paper examines the notion that trust plays a key role in making a seller's …

A review of the present status of the theory of magnetic reconnection is given. In strongly
collisional plasmas reconnection proceeds via resistive current sheets, ie quasi-stationary …

A three-dimensional, self-consistent numerical model of the geodynamo is described, that
maintains a magnetic field for over 40,000 years. The model, which incorporates a finitely …

We study numerically an extensive set of dynamo models in rotating spherical shells,
varying all relevant control parameters by at least two orders of magnitude. Convection is …

We present the first three-dimensional (3D), time-dependent, self-consistent numerical
solution of the magneto-hydrodynamic (MHD) equations that describe thermal convection …

A new kind of overset grid, named Yin‐Yang grid, for spherical geometry is proposed. The
Yin‐Yang grid is composed of two identical component grids that are combined in a …

Abstract 80 years ago, Joseph Larmor planted the seed that grew into today's imposing body
of knowledge about how the Earth's magnetic field is created. His simple idea, that the …

We present the results of a benchmark study for a convection-driven magnetohydrodynamic
dynamo problem in a rotating spherical shell. The solutions are stationary aside from …
