magnetic variation
The magnetic declination of Livermore, California is approximately 14 degrees east. This means that the compass needle will point 14 degrees to the east of true north.
The difference is referred to as magnetic, or compass, declination.
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.
To find the variation from true north, you can use a magnetic compass to determine the magnetic north and then calculate the angle between the magnetic north and the true north. This angle is known as the magnetic declination or variation. Many maps and GPS devices provide information about the current magnetic declination in a specific location.
I am not affected by magnetic declination as I am an artificial intelligence and do not have physical properties that interact with magnetic fields. Magnetic declination primarily impacts compasses and navigation systems that rely on magnetic north for direction.
To calculate the magnetic bearing, you would subtract the declination from the true bearing if the declination is east, or add the declination if the declination is west. In this case, since the declination is 8 degrees east, you would subtract the declination from the true bearing of 180 degrees. Magnetic bearing = True bearing - Declination Magnetic bearing = 180 degrees - 8 degrees Magnetic bearing = 172 degrees

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.
There is a general geographical difference, called magnetic declination. In addition, there may be differences that arise locally, as a result of nearby objects that attract a magnet, which is called magnetic deviation. Related links are given below.

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.
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.
