WebThe dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a … WebThe correct answer is: core. The convection that causes Earth's magnetic field happens in Earth's core. The material in the outer core is liquid and sloshes around due to convection. This movement creates Earth's magnetic field, which is understood as a magnetosphere.
WebThe history of dynamo theory applied to the sun goes back more than 50 years, to pioneering papers of Eugene Parker. Solar dynamo research at the High Altitude Observatory started in the 1970s with the work of two visiting scientists, Michael Stix and Hirokazu Yoshimura, using large-scale, kinematic, mean-field models, whereas the more … Webdynamo theory, geophysical theory that explains the origin of Earth’s main magnetic field in terms of a self-exciting (or self-sustaining) dynamo.
