WebA) dynamo action, like the Earth’s magnetic field. B) a mechanism entirely unique to Mercury. C) being close to the Sun. D) being a fossil remnant dating back to the distant past when the core was more liquid. Answer: A. Which of these theories seems to best explain the Moon’s origin? A) Impact Theory B) Capture Theory C) Coformation Theory Dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid acts to maintain a magnetic field. This theory is used to explain the presence of anomalously long-lived magnetic fields in astrophysical bodies. The conductive fluid in the geodynamo is liquid iron in the outer core, and in the solar dynamo is ionized gas at the tachocline. Dynamo theory of astrophysical bodies uses magnetohydrodynamic equations to investigate ho…

WebApr 30, 2024 · Summary. The solar dynamo is the action of flows inside the Sun to maintain its magnetic field against Ohmic decay. On small scales the magnetic field is seen at the solar surface as a ubiquitous “salt-and-pepper” disorganized field that may be generated directly by the turbulent convection. On large scales, the magnetic field is … WebJun 16, 2000 · Dynamo action occurs inside the tangent cylinder through a combination of zonal and helical flows. Upwelling along the rotation axis causes divergence of flow at the core-mantle boundary and a westward circulation by conservation of angular momentum. At the inner-core boundary, a convergent flow produces an eastward circulation, which is ...
