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.
Most of Alabama lies along the declination zero line. So, there is no declination adjustment needed in Alabama.
Variation in the Earth's magnetic field: The outer core of the Earth is in constant motion, leading to changes in the magnetic field over time, causing magnetic declination. Local magnetic anomalies: Presence of magnetic minerals or man-made structures in the vicinity can distort the Earth's magnetic field, affecting the accuracy of the compass reading. Distance from magnetic poles: The closer one is to the magnetic poles, the greater the magnetic declination due to the convergence of field lines.
Knowing an area's magnetic declination is important for accurate navigation using a magnetic compass. Magnetic declination indicates the angular difference between magnetic north and true north, helping to correct for compass errors. This information is crucial for precise orientation in outdoor activities such as hiking, camping, and boating.
Magnetic declination changes over time due to fluctuations in the Earth's magnetic field. The rate at which it changes depends on the location on the Earth's surface. In general, the change is relatively slow, with typical variations of a few minutes to a few degrees over a decade.
The amount a compass needle deviates from true north is known as magnetic declination. This angle can vary depending on your location on Earth and is caused by variances in the Earth's magnetic field. It is important to adjust for magnetic declination when using a compass for accurate navigation.
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.

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.
