WebThere is one theory that explains how the earth’s magnetism is caused: Dynamo effect: The earth gets its own magnetic field lines because of the presence of the metallic fluids that are present at the outer core as well as in the inner core. The outer core consists of molten iron, while the inner core has the solidified elements. Web7 mrt. 2024 · The Earth has a solid inner core and a liquid outer core, both made of iron and nickel. The metal carries an electrical current that is powered by the movement of the liquid. The electrical current creates a magnetic field that reaches out from the core to the surface of the Earth and beyond.
