Theres a wide variety see this and this reviews of magnetohydrodynamical models with different assumptions parameter ranges boundary conditions etc that successfully describe main characteristics of Earths magnetic field dynamics. What is the Earths magnetic field is known as a. The World Magnetic Model WMM the name of the updated representation of the magnetic field of Earth is expected to be released no earlier than Jan.
In summary it states that the Earths magnetic field is generated by movements stirred up by the Earths rotation known as convection currents in the outer core which is liquid and because it is made out of iron is a good conductor of electricity. It protects us from some of the harsher aspects of. According to a paleomagnetic study of the Australian red dacite and pillow basalt the magnetic field has been estimated to be at least 35 billion years old.
It is the innermost part formed by very heavy metals in a plastic or liquid state whose rotation forms the planets magnetic field. Created by the churn of Earths core this field is important for everyday life. The earths magnetic field extends millions of kilometers into outer space and looks very much like a bar magnet.
At the equator the lines. At the magnetic poles the lines. Below that it is all clear to the surface.
Extending from Earth like invisible spaghetti is the planets magnetic field. We never see it but the Earths magnetic field is one of the things that allow life to thrive on our planet. The geomagnetic field varies on a range of scales and a description of these variations is now made in the order low frequency to high frequency variations in both the space and time domains.
