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.
The magnetic variation is greatest on earth at greggs in pakistan.... no need to thank me for the answer
Absolutely none.
It will be 180 degrees in any position between the north magnetic pole and the geographical north pole and similar at the south pole
Magnetic anomalies occur where vast deposits of iron ore have caused a local deviation in the Earth's magnetic field.Any place where the Earth's magnetic field is not smooth and uniform.Some are so minor that they can't be detected without a million dollars worth of fancy equipment, some you can detect with a pocket compass.
They would not arrive at the correct location. True north refers to the rotational pole. Compasses point roughly towards the magnetic pole. I say roughly because geographic and man made features can distort the magnetic waves. The rotational and magnetic pole are not at the same place. Most maps are drawn according to the rotational pole (true north).
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.
Percent variation is the standard deviation divided by the average
standard deviation only measures the average deviation of the given variable from the mean whereas the coefficient of variation is = sd\mean Written as "cv" If cv>1 More variation If cv<1 and closer to 0 Less 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.
Wave length of light varies with color and due to variation of wavelength velocity varies .so different colors have different deviation
Coeff of Variation = Mean/SD
The standard deviation is a measure of the spread of data.
Deviation = A full change from the Original (depending on what you're deviating from), while Variation = a change of small or fairly insignificant magnitude from the Original.
One the main advantage of using the coefficient of variation over the standard deviation to measure volatility is the fact that CV is normalized and can be used to directly compare different asset's volatility. The standard deviation must be used in the context of the mean of the data.
Yes, it is commonly known as magnetic deviation
