Your magnetic compass does not actually point north, it merely aligns itself with the lines of magnetic force at your location. These do not necessarily point to the North - they may differ by some tens of degrees. This difference is the Magnetic Declination.
On hikers maps, you'll find that the true north of the map is shown as well as the magnetic declination at that region. The declination itself changes slowly, too slow for you to bother with its changing.
What else can I help you with?
In order to find true north with a compass you must use an angle of correction called?
angle of magnetic declination
What is a good sentence using the word common?

What is an example of an exclamatory sentence using the word happening?
This is an example of an exclamatory sentence using the word happening!
What is a sentence using the word oversimplification?
a good sentence is "I cannot use oversimplification in a sentence." that sentence is oversimplification.

What is the angle declination in surveying?
Angle declination in surveying refers to the difference between the true north and the magnetic north at a specific location. It is important to account for this declination when using compasses or other magnetic instruments to ensure accurate measurements and calculations.
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 magnetic declination for Seattle?
For Seattle, the magnetic declination is approximately 14 degrees East. This means that magnetic north is about 14 degrees to the east of true north in Seattle. It is important to consider this when using a magnetic compass for navigation in the area.
Why is magnetic Declination is important?
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.
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
What is the magnetic declination in Miami?
No
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.
Why is it important to know an area's magnetic declination?
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.
What is The discrepancy between the orientation of a compass and true north known as?
The discrepancy between the orientation of a compass and true north is known as declination. It is caused by the difference between the Earth's magnetic field and its geographic North Pole. To navigate accurately, this declination value needs to be factored in when using a compass for navigation.
What would your magnetic declination be if you were using a compass in Vail Colo.?
9 degrees 32 minutes EAST (positive)
Why is it important to know magnetic declination when using a compass?
Knowing the magnetic declination is important when using a compass because it helps you correct for the difference between magnetic north (the direction the needle points) and true north (the direction of the North Pole). Failing to account for this difference can lead to navigational errors when trying to follow a specific heading on a map.
The angle of difference between the geographic and magnetic poles is called the declination How does the declination change as you move north from where you live?
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.
