Geomagnetic field
Geomagnetic field, that is, the earth as a magnetic dipole (magnetic dipole), one pole in the vicinity of the geographical north, the other pole in the geographical near the Antarctic, the poles generated by the magnetic field is the magnetic field; The magnetic axis of the magnetic pole is about 11.3 degrees inclined to the earth's rotation axis. The cause of the geomagnetic field may be explained by the principle of the generator. Geomagnetic field in the surface strength of 0.3 Gauss to 0.6 Gaussian, to space is tens of thousands of kilometers out of the formation of the Earth's magnetic circle, the role of solar wind protection. ...
