The Malkus–Robbins dynamo with a linear series motor [PDF]

open access: yes, 2003
Hide [1997] has introduced a number of different nonlinear models to describe the behavior of n-coupled self-exciting Faraday disk homopolar dynamos. The hierarchy of dynamos based upon the Hide et al.

Magnetic Signatures of Large-Scale Electric Currents in the Earth’s Environment at Middle and Low Latitudes

open access: yesAtmosphere, 2022
The purpose of space weather is the systemic study of the Sun–Earth system, in order to determine the impact of solar events on the electromagnetic environment of the Earth.

The solar dynamo [PDF]

open access: yesInternational Astronomical Union Colloquium, 1991
AbstractThe traditionalαΩ-dynamo as a model for the solar cycle has been successful in explaining the butterfly diagram, phase relations between poloidal and toroidal field, and polar branch migration features. Observational and theoretical achievements in recent years have however shaken this picture.

Magnetic field amplification to gigagauss scale via hydrodynamic flows and dynamos driven by femtosecond lasers

open access: yesNew Journal of Physics, 2021
Reaching gigagauss magnetic fields opens new horizons both in atomic and plasma physics. At these magnetic field strengths, the electron cyclotron energy ℏω _c becomes comparable to the atomic binding energy (the Rydberg), and the cyclotron frequency ω ...

Prandtl-number dependence of convection-driven dynamos in rotating spherical fluid shells [PDF]

open access: yes, 2005
The value of the Prandtl number P exerts a strong influence on convection-driven dynamos in rotating spherical shells filled with electrically conducting fluids.

Magnetic Stability Analysis for the Geodynamo [PDF]

open access: yes, 2004
Kinematic dynamo modelling addresses the growth of magnetic fields under the action of fluid flow, effected in the geophysical case by the action of the convecting electrically conducting outer core and magnetic diffusion. In this study, we prescribe the

Dynamic Modeling of Indole Glucosinolate Hydrolysis and Its Impact on Auxin Signaling

open access: yesFrontiers in Plant Science, 2018
Plants release chemicals to deter attackers. Arabidopsis thaliana relies on multiple defense compounds, including indol-3-ylmethyl glucosinolate (I3G), which upon hydrolysis initiated by myrosinase enzymes releases a multitude of bioactive compounds ...

On energetics and inertial-range scaling laws of two-dimensional magnetohydrodynamic turbulence [PDF]

open access: yes, 2012
L. Blackbourn was supported by an EPSRC post-graduate studentship.We study two-dimensional magnetohydrodynamic turbulence, with an emphasis on its energetics and inertial range scaling laws.

The Solar Dynamo and Planetary Dynamo [PDF]

open access: yesSymposium - International Astronomical Union, 1993
A dynamo driven by flows of differential rotation and global convection in a rotating sphere is reviewed as a model of the solar and planetary dynamos. The flows can amplify a magnetic field from an infinitesimal level and thus can generate a magnetic field.

Cio-cio-san no Yūutsu: memoirs of magnetogenesis and Turbulent Dynamo Theory [PDF]

open access: yes, 2013
The origins of cosmic magnetic fields are not as yet well understood. In this dissertation we investigate, via direct numerical simulation, the temporal evolution and behaviour of magnetic fields that are generated from absolute zero initial conditions ...
