Description : What makes the earth's magnetic field? If, for some reason, this magnetic field were to go away, would it be a problem for the living world?
Last Answer : It is certainly not known why and why the earth has a magnetic field, we can only guess that the earth's magnetic field was formed by the earth's core or by deeply compressed metals, which ... would have no fatal consequences for wildlife, only for people with their technical gadgets at most. :)
