Dynamo theory

Webダイナモ理論（ダイナモりろん、英: dynamo theory ）とは、地球や太陽などの天体が内部の流体運動によって大規模な磁場を生成・維持する働きを記述する理論である。 ダイナモ効果、ダイナモ作用とも呼ばれる。天体の磁場は、大規模な電流によって支えられているという意味で、電磁石である ... WebTheory of Earth’s Magnetism. There is one theory that explains how the earth’s magnetism is caused: Dynamo effect: The earth gets its own magnetic field lines because of the presence of the metallic fluids that are present at the outer core as well as in the inner core.
