SUMMARY
The Earth develops its magnetic field primarily through two mechanisms: the movement of the molten iron core and the interaction of solar wind with the upper atmosphere. These processes generate electric currents, resulting in an electromagnetic field that varies over time. While the dynamo effect creates a relatively stable magnetic field, the components influenced by ionosphere and solar interactions exhibit significant variability. Therefore, it is accurate to refer to Earth's magnetic field as an electromagnetic field.
