The magnetized needle of a compass usually does not point towards thegeographical North Pole, ortrue north. Rather, it aligns itself with the direction of the Earth's magnetic field, showingmagnetic north. In most locations on Earth, magnetic north differs from true north, so magnetic declination...
Historically, the magnetic compass was an important tool for navigation. The compass aligns itself with the local geomagnetic field. It shows neither the north magnetic pole nor the geographic north pole (true north). Image:PXHere Update: North Magnetic Pole officially has a new location National ...

Magnetic North Versus True North The needle on your magnetic compass points not at the true North Pole, but at a point that is presently about 500 kilometers (about 310 miles) from the North Pole, on Ellesmere Island in northern Canada. This is owed to the presence of a large deposit of...
True Meridian The direction from any point along a meridian towards the North Pole of the earth is defined as true north. That is, the north according to the earth’s axis. True north is also known as geographic north. True south is also defined in a similar manner. True meridian is de...
The meaning of MAGNETIC POTENTIAL is the scalar quantity characteristic of a point in a magnetic field whose negative gradient equals the intensity or strength of the magnetic field and which represents the work required to bring a unit north pole from a
They both include fundamental polarization – North and south magnetic pole, positive and negative charge. Lets assume, we have two exactely equal amounts/quants of matter than can be magnetized. Both consist of the same amount of atoms, the same amount of electrons, protons, neutrons, quarks...
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...

All the spins in this figure are spin-1/2 and the Bloch spheres are oriented such that their north pole represents the source state \(\left| {1/2} \right\rangle\). In each case, the position and orientation of the probe spins are marked on the shell of the spheres. The minimal, ...
