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...

North pole B. South pole C. East pole D. West pole Correct Answer A. North pole Explanation The reason the north pole of a magnet points toward the geographic north when freely suspended is due to the Earth's magnetic field. The Earth itself acts like a giant magnet with a magnetic sou...
Earth's magnetic north pole, vs. true/geographic north pole As you probably remember from high school, the Earth is a giant bar magnet -- a magnetic dipole with the north pole in the north, and the south pole in the south. If you imagine that there's really a...
Earth has three distinct north poles. Thegeographic north poleis centred at the exact 'top' of the planet and never moves. Thegeomagnetic north poleis where Earth's magnetic field would appear to be focused in the nor...
Finally, for animals such as birds that can potentially perceive the direction of true geographic north (e.g., using star patterns to determine Earth’s axis of rotation), additional magnetic parameters such as declination (the difference between true north and magnetic north) might also be used...
