Theoritical value of earth magnetic field
Webb24 apr. 2016 · The generally accepted theory is known as the dynamo theory. The details of the theory are rather complex. In summary, it states that the Earth’s magnetic field is generated by movements stirred up by the Earth’s rotation known as “convection currents” in the outer core, which is liquid and, because it is made out of iron, is a good ...
