Dynamo and Hydromagnetic LiquidMetal Experiments
Magnetic dynamo experiments are being performed in many laboratories throughout the world. The most successful have been at Kalsruhe and Riga where liquid sodium has been forced in constrained flows and produced predicted postive dynamo gain. The unconstrained flows are being investigated at Wisconsin, Cadarache , and Maryland. These experiments have not reached the critical values of the magne...
متن کاملSolar Dynamo Theory
TheSun’smagnetic field is the engine and energy source driving all phenomena collectively defining solar activity, which in turn structures the whole heliosphere and significantly impacts Earth’s atmosphere down at least to the stratosphere. The solar magnetic field is believed to originate through the action of a hydromagnetic dynamo process operating in the Sun’s interior, where the strongly ...
متن کاملOutstanding Issues in Solar Dynamo Theory
The magnetic activity of the Sun, as manifested in the sunspot cycle, originates deep within its convection zone through a dynamo mechanism which involves non-trivial interactions between the plasma and magnetic field in the solar interior. Recent advances in magnetohydrodynamic dynamo theory have led us closer towards a better understanding of the physics of the solar magnetic cycle. In conjun...
متن کاملDynamo Theory and Earth’s Magnetic Field
The Earth’s magnetic field belongs in that class of physical phenomena which are commonplace yet also very complex. It is commonplace in that almost everyone knows that it exists, yet not very many people (probably including a good percentage of physicists) know how it works. The theory behind the generation of a magnetic field, known as dynamo theory, is still an active area of research. The e...
متن کاملMHD dynamo generation via Riemannian soliton theory
Heisenberg spin equation equivalence to nonlinear Schrödinger equation recently demonstrated by Rogers and Schief , is applied to the investigation of vortex filaments in magnetohydrodynamics (MHD) dynamos. The use of Gauss-Mainard-Codazzi equations allows us to investigate in detail the influence of curvature and torsion of vortex filaments in the MHD dynamos. This application follows closely ...
