发电机理论或发电机原理(英语:Dynamo theory)是一个关于天体磁场的假说,人们相信地球磁场是由于地球外核中熔融铁、镍的对流以及整个行星自转的科里奥利力作用造成的。当导电流体流经已形成的磁场时,会产生电磁感应及其磁场。感应磁场对原磁场有补偿作用,如此一来可维持自身电力的发电机就形成了。类似的磁场在太阳(含有等离子体)、金星等天体上也存在。
继而从发电机理论得到了电离层电位及层电流密度在北半球的分布和变化。
Furthermore the distribution and variation of the electrostatic potential and layer ionospheric current density at the northern hemisphere are calculated by the dynamo theory.
