WebThe Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a "magnet."

WebJul 6, 2024 · It is continuously generated by the motion of liquid iron in Earth’s outer core, a phenomenon called the geodynamo. Despite its fundamental importance, many questions remain unanswered about the geodynamo’s origin and the energy sources that have sustained it over the millennia. WebJun 16, 2024 · Why does the Earth even have a magnetic field? At the risk of oversimplifying a bit, the answer is the dynamo theory. Convection in an electrically conductive, rotating fluid – in this case, the molten metal in the planet's core – creates electric currents that, in turn, generate a magnetic field. Why doesn't the same thing happen in the oceans?
