Web17 apr. 2024 · At middle and low geomagnetic latitudes (below 60) the dynamo mechanism is believed to be the primary source of ionospheric currents and electric fields, as well as ground-level magnetic variations, on geomagnetically quiet days. Web24 okt. 2024 · It's called a "self-exciting dynamo effect," where a dynamo is a simple type of electric generator. Molten iron is not the only factor in the Earth's magnetic field, the crust, ionosphere, and magnetosphere also can influence it.
