Because if you need to use your compass to figure out which direction is north,
then you need to know by how much the direction the compass points is wrong,
and which way. That's the magnetic declination.
+15° 45'
when you are close to the magnetic north pole, the declination will be so variable and unpredicatable that a magnetic compass becomes all but useless. You also need to consider the effect of local magnetic anomalies and polar wandering. felicity knows whats up<3
Inclination is measured as the angle at which the satellite crosses the equator while passing from the southern hemisphere to the northern hemisphere. Declination is the difference between magnetic North as reported by a compass and true North.
The angle between the geographic and magnetic poles extends more towards the east, as you move to the north. The magnetic pole is actually near Greenland.
Between 14 and 16 degrees East, depending on location (16 degrees on the coast, 14 near Ontario)
It may not be important, but it IS a matter of wide interest, because it determines the length of daylight and darkness everywhere on Earth, as well as the onset of each change of seasons.

Assuming the subject is magnetic declination the difference between the north pole and the true north pole this difference, is the magnetic declination, there is not information on what purpose it serves.

Magnetic Declination
12E
The magnetic declination in Jasper, Alberta, Canada is approximately 18 degrees east. This means that magnetic north is 18 degrees east of true north in this location.
magnetic variation
23
The magnetic declination of Spokane Valley is approximately 16 degrees east. This means that magnetic north is about 16 degrees east of true north in that location.
