In the Forschungszentrum Karlsruhe an experiment has been constructed which demonstrates a homogeneous dynamo as is expected to exist in the Earthâ€™s interior. This experiment is discussed within theâ€¦ (More)

(Received 00 Month 200x; in final form 00 Month 200x) Mean-field theory describes magnetohydrodynamic processes leading to large-scale magnetic fields in various cosmic objects. In this studyâ€¦ (More)

Aims. The test-field method for computing turbulent transport coefficients from simulations of hydromagnetic flows is extended to the regime with a magnetohydrodynamic (MHD) background. Methods. Aâ€¦ (More)

The predictive power of mean-field theory is emphasized by comparing theory with simulations under controlled conditions. The recently developed test-field method is used to extract turbulentâ€¦ (More)

Meanâ€“field electrodynamics: Critical analysis of various analytical approaches to the mean electromotive force There are various analytical approaches to the mean electromotive force E = u Ã— bâ€¦ (More)

The effect of a dynamo-generated mean magnetic field of Beltrami typ e on the mean electromotive force is studied. In the absence of the mean magnetic field the turbule nce is assumed to beâ€¦ (More)

When scale separation in space and time is poor, the Î± effect and turbulent diffusivity have to be replaced by integral kernels. Earlier work in computing these kernels using the test-field method isâ€¦ (More)

We study the stability/establishment of dipolar magnetostatic equilibrium configurations in newâ€“born neutron stars (NSs) in dependence on the rotational velocity Î© and on the initial angle Î± betweenâ€¦ (More)
