WebThe Earth's magnetism is no exception, and its energy seemes to come from fluid motions in the Earth's core, from circulating flows that help get rid of heat produced there. In a … 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 … See more When William Gilbert published de Magnete in 1600, he concluded that the Earth is magnetic and proposed the first hypothesis for the origin of this magnetism: permanent magnetism such as that found in See more 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 … See more Broadly, models of the geodynamo attempt to produce magnetic fields consistent with observed data given certain conditions and equations as mentioned in the sections above. Implementing the magnetohydrodynamic equations … See more • Antidynamo theorem • Rotating magnetic field • Secular variation See more In kinematic dynamo theory the velocity field is prescribed, instead of being a dynamic variable: The model makes no provision for the … See more The kinematic approximation becomes invalid when the magnetic field becomes strong enough to affect the fluid motions.
