WebNov 24, 2013 · In the kinematic regime the magnetic energy spectrum develops a k 3/2 power law at large scales, so the spectral magnetic energy peaks at small scales. As the dynamo saturates, the magnetic energy spectrum approaches the k-5/3 power law of the turbulent flow and saturates. Thus, also the magnetic energy spectrum gradually … WebOther articles where dynamo effect is discussed: plasma: Applications of plasmas: One suggestion depends on the dynamo effect. If a plasma moves perpendicular to a magnetic field, an electromotive force, according to Faraday’s law, is generated in a direction …
WebMar 3, 2024 · Related to the expression of EMF, the physical origin of the cross-helicity effect in dynamos, as well as other dynamo effects, is discussed. In order to understand the actual role of the turbulent cross helicity, its transport equations is considered. Several generation mechanisms of cross helicity are discussed with illustrative examples.
In physics, the dynamo theory proposes a mechanism by which a celestial body such as Earth or a star generates a magnetic field. The dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a magnetic field over astronomical time scales. A dynamo is thought to be the source of the Earth's magnetic field and the magnetic fields o… WebThe problem of “fast dynamos” in the limit of large magnetic Reynolds number is studied by Childress and Gilbert in “Stretch, twist, fold: the fast dynamo” 9.
