Where is magnetic variation greatest on Earth?
The magnetic variation is greatest on earth at greggs in pakistan.... no need to thank me for the answer
Different magnetic deviation and magnetic variation?
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.
What effect does magnetic variation have on the earths orientation?
Absolutely none.
Why does the earth have its own magnetic field?
The Earth's magnetic field is probably caused by convective currents in Earth's interior.
When magnetic flux through surface is maximum?
Magnetic flux through a surface is maximum when the direction of the magnetic field is in the same direction as the normal vector of the surface. In other words, the magnetic flux is maximum when the magnetic field is perpendicular to the surface area. That's why φ=BAcosθ, where θ is the angle between the direction of the magnetic field and the normal vector of the surface area. When the magnetic field is exactly the same direction as the normal vector (aka the magnetic field is perpendicular to the surface), θ=0 and cosθ = 1, its maximum value. The closer θ is to 90 degrees (ie. the more parallel the direction of the magnetic field is to the surface area, or the less parallel the magnetic field is to the surfaces normal vector), the smaller cosθ is, and thus flux will decrease accordingly.

What is magnetic variation?
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.
What is the angular difference between true North and magnetic North is called?
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.
What is happening to earths magnetic field?
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.
Imaginary band connects two points on earth's surface with zero magnetic variation?
The Equator
What is the magnetic variation for 2009?
It depends on the place on earth you are. In my place (Israel) 32.09N 34.47E it is around 4 deg East.
What is the compass variation?
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.
If in Crete Greece what would the magnetic variation be?
The magnetic variation of Crete is approx. 3.2 degr EAST Greetings, Dimitris
What is the Is the difference between true North and magnetic north?
magnetic variation
How does one measure 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).
What is the name given to the difference between true north and magnetic north?
magnetic variation
What is the difference in degrees between True North and Magnetic NOrth on the topographic map?
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.
