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. WebDec 19, 2024 · There are four known fundamental forces of nature – gravity, electromagnetism, and the strong and weak nuclear forces that exist within atomic nuclei. Of these, gravity is too weak to be useful as a localised force field – it takes all the gravity produced by our planet, the Earth, to stick our relatively puny bodies to its surface.
