Dynamo effect earth's magnetic field
WebDec 22, 2011 · Measurements made by Mariner 10 in 1974/75 showed that Mercury also has a magnetic field. According to the standard models, the dynamo effect in its metal core should generate similar field strengths to those on Earth. Mercury’s magnetic field is 150 times weaker than that of our planet, however. This has recently been confirmed by … 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 …
