The difference between True North and the direction that a magnetic compass points for a given location. Example: the magnetic declination for Seattle, Washington per the NOAA is 16° 55' east (as of 04/2010). This means that magnetic north is predicted at 16° 55'east of True North at that time.

A way to find the variation from true north?
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.
How do you convert true bearings to magnetic?
To convert true bearings to magnetic bearings, you need to account for the magnetic declination (also known as magnetic variation) at your location. If the magnetic declination is east, you subtract it from the true bearing; if it is west, you add it. For example, if your true bearing is 100° and the magnetic declination is 5° east, the magnetic bearing would be 95°. Always check local charts or resources for the most accurate declination values.
Where is magnetic declination the worst?
Magnetic declination, or the angle between magnetic north and true north, is typically most pronounced in areas near the magnetic poles. This includes regions like northern Canada and parts of northern Russia, where the magnetic field lines are more vertical and can lead to significant variations in declination. Additionally, areas around the equator may also experience notable declination changes due to the complex interactions of the Earth's magnetic field.
What happens to the angle of declination when you are closer to the poles?
As you move closer to the poles, the angle of declination increases. This is because the Earth's magnetic field lines are more vertical near the poles, causing the magnetic declination— the angle between magnetic north and true north—to become more pronounced. In extreme polar regions, the declination can approach 90 degrees, where magnetic north aligns closely with the vertical orientation of the Earth's magnetic field.
What is the name given to the difference between true north and magnetic north?
magnetic variation
Calculate the magnetic bearing from a true bearing of 180 degree from a map with declination of 8 degrees east?
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
How are you affected by magnetic declination?
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.

What is the purpose of a declination?
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.

In what part of North America is the magnetic declination greatest?
The magnetic declination is greatest in the northern part of North America, particularly in areas close to the magnetic North Pole. This includes regions of northern Canada and Alaska, where the declination can exceed 20 degrees. As one moves southward, the declination generally decreases.
What is the angular difference between true North and magnetic North is called?
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.
What is the angle of correction called?
Magnetic Declination
What is magnetic declination for Los Angeles?
12E
What is the Declination between true and magnetic north for San Angelo Texas?
As of my last update, the declination between true north and magnetic north in San Angelo, Texas, is approximately 4 to 5 degrees east. However, magnetic declination changes over time due to shifts in the Earth's magnetic field. For the most accurate and current information, it's advisable to consult a magnetic declination map or an online calculator.
Where geographically is magnetic declination the worst?
Magnetic declination is typically worst near the magnetic poles, particularly within the Arctic and Antarctic regions. In these areas, the angle between magnetic north and true north can vary significantly, leading to more pronounced declination values. Additionally, regions with complex geological structures or significant magnetic anomalies, such as areas with large mineral deposits, can also experience heightened declination effects.
