It will be 180 degrees in any position between the north magnetic pole and the geographical north pole and similar at the south pole
The magnetic variation is greatest on earth at greggs in pakistan.... no need to thank me for the answer
In relation to aviation... Deviation is the difference between a true heading and the compass heading. The compass heading is different from true due to magnetic fields induced by the components of the aircraft. Variation is the difference (angle) between True North and Magnetic North. Variation changes depending on your position and is normally indicated on maps as a dashed line with the variation in degrees along that particular line.
Absolutely none.
The Earth's magnetic field is probably caused by convective currents in Earth's interior.
what characteristic of earth's interior is likely to be responsible for earth's magnetic field

Since the Earth's magnetic poles are not located at the geographic poles, a magnetic compass doesn't point to 'true' (geographic) north. The DIFFERENCE angle between magnetic north and true north is the magnetic variation or declination where you are. It changes for different locations.
That's the "magnetic declination". Since the true north pole and the magnetic north pole are located at different points on the earth, the declination is a different angle in different places on earth.
In early 2014, scientists have discovered that the Earth's magnetic field has been weakening for some time. This could eventually lead to the switching of the Earth's magnetic poles.
The Equator
It depends on the place on earth you are. In my place (Israel) 32.09N 34.47E it is around 4 deg East.
The magnetic variation of Crete is approx. 3.2 degr EAST Greetings, Dimitris
I think you're after the magnetic variation. If so :- That is the variation between true north and the earth's magnetic field at your location. Can be + or - and up to a few tens of degrees.Your compass does not actually point to north, though that is a useful assumption. In reality, the compass needle aligns itself with the direction of the earth's magnetic lines of force at your location. These do not run nicely north and south. Your map will have on it an indication of the magnetic variation in that region, and may include also the amount by which that varies annually.The earth's magnetic field is generated (most of it anyway) by electrical currents flowing in the magma. These currents may be caused by the core rotating slightly faster than the mantle and crust. [But no one's been there!] The magma and the earths core beneath it are much too hot to sustain a magnetic field.
magnetic variation
Magnetic variation (also known as magnetic declination) is often indicated on maps. But if the magnetic variation of a location is unknown, a declinometer can be used. Basically, this tool determines the angle between the celestial pole (roughly indicated by the North Star in the northern hemisphere) and the magnetic pole (indicated by a compass).
magnetic variation
It varies with where you are on the earth. It all has to do with your geographic position (lat/lon) and also the magnetic activity of the area. You can acquire a USGS topographical map and it will have the magnetic variation for the area shown.
