【题目】请教一下地理北极geographic north pole地磁北极geomagnetic north pole磁北极magnetic north po le的区别其实看到这样一句话“地磁北极在地理南极附近,地磁南极在地理北极附近”,但是我现在看到一个叫做磁北极magnetic north pole的概念,和地磁北极geomagnetic north pole的概念不一样。请您看这个图,这个图明显表明...
关于磁北极和北磁极的理解如下：磁北极（Geomagnetic North Pole）这点是地球北半球的偶极子，偶极子就是长型磁铁的2个极端叫偶极子，约9.6°倾斜对地球的旋转轴。北磁极（North Magnetic Pole）这个点约每天20m的移动速度在跑，随着地球内部的地磁变化而变动；这个点的定义是北半球表面指南针会垂直指向...

The South Magnetic Pole also moves in a similar fashion. But, since the Earth’s magnetic field is not exactly symmetrical, unlike the geographic north and south poles, the North and South Magnetic Poles are not antipodal, meaning that a straight line drawn from one to the other does not p...

If you have ever used a compass, you know it points to the north. But did you know it usually doesn't point to the geographic North Pole or to the magnetic North Pole? North on a compass can deviate from true north. ©bigstockphoto.com/Remains ...
A magnetic compass needle will always point to magnetic north. To calibrate a compass properly, you must understand that magnetic north and true north are not the same directional value. In fact, magnetic north is approximately 1,000 miles away from the
The north magnetic pole (磁极) is no longer a resident of Canada. It has drifted across the Canadian Arctic and is now angling toward Siberia. Not to be confused with the geographic North Pole — the northern extremity of the Earth's axis (地轴), the north magnetic pole (where the Earth...
If your compass does not have the ability to adjust, then lay it on the map in line with the grid lines and rotate the map until the north needle points to 340 degrees, which is 20 degrees west of North, matching your local declination. Then, map north and geographic north are ...
