信息链接:地磁场是地球物理学的基本问题之一,地磁场产生的原因尚无定论,普遍认为是由地核内液态铁的流动引起的,还有一种假说应用“磁现象的电本质”来做解释,认为地核在6000 K的高温和360万个大气压的环境中会有大量的电子逃逸出来,地幔间会形成负电层,地球自转造成地幔负电层旋转产生环形电流,地磁场由此而生.地磁场在某处的磁感应强度、磁偏角(磁子午线与地理子午线间的夹角)、磁倾角(地磁场方向与地面水平方向间的夹
Information Links: Earth’s magnetic field is one of the basic problems of geophysics. The cause of the geomagnetic field is not determined. It is generally believed that this is caused by the flow of liquid iron in the Earth’s core. There is also a hypothesis that the electrical nature of magnetic phenomena "To explain that the Earth’s core at 6000K high temperature and 3.6 million atmospheric environment will have a large number of electrons escaped from the mantle will form a negative layer, the Earth’s rotation caused by the negative rotation of the mantle ring current, geomagnetic field The resulting magnetic field at somewhere the magnetic flux density, magnetic declination (magnetic meridian and the angle between the geographical meridian), magnetic inclination (magnetic field direction and the ground level between the folder
