发电机原理 Dynamo theory

（重定向自Dynamo Effect）

发电机原理是一个关于天体磁场的假说，对于地球来说，人们相信，磁场是由于地球外核内的熔化了的铁和镍的对流以及整个行星自转的科里奥利力作用造成的。当导电流体流经一个已经存在的磁场时，会产生电磁感应及其磁场。感应磁场会对原磁场有补偿作用，这样一个可以维持自身的发电机就形成了。类似的磁场在太阳（含有等离子体）等天体上也存在。

Dynamo theory 发电机原理

（重定向自Dynamo Effect）
Illustration of the dynamo mechanism that creates the Earth's magnetic field: convection currents of magma in the Earth's outer core, driven by heat flow from the inner core, organized into rolls by the Coriolis force, creates circulating electric currents, which generate the magnetic field.[1]

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, as well as the magnetic fields of other planets.
