地理北极：是指北极点，是指地球自转轴穿过地心与地球表面相交，并指向北极星附近的交点。地磁北极：地球是一个具有磁场强度不均匀变化的球体，19世纪20年代，德国著名数学家高斯(K. F. Gauss)发表了关于地球磁场的理论，将地球视为一个具有均匀磁场强度的球体而用数学推导出的磁极，称为地球的地磁南北极...

The direction of the flux is the direction in which the north-seeking pole of a small magnet points. The lines of flux are continuous, forming closed loops. For a bar magnet, they emerge from the north-seeking pole, fan out and around, enter the magnet at the south-seeking pole, and ...

Magnetic pole reversal Magnetic fields on other planets Additional resources Earth's magnetic field — also known as the geomagnetic field — is generated in our planet's interior and extends out into space, creating a region known as the magnetosphere. Without the magnetic field, life on ...
By the time we die -- or at least when our children die -- the north pole might be in the south. NASA's simulation of what Earth's magnetic fields might look like during a geomagnetic reversal Sadly, we can only guess at what actually happens to Earth -- and...

(the curving line across the earth), field lines run parallel to the earth’s surface. Field lines become progressively steeper as one travels north toward the magnetic pole, where the field lines are directed straight down into the earth and the inclination angle is 90°. The intensity (...
