Zero.
That's not precisely true, but if you really need a precise value you'd already know better than to ask what the declination was for an area as large as the state of Missouri. The agonic line (where the declination is precisely zero) does currently run through Missouri, so the value is less than a degree or two for essentially the whole state.
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.
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.
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
The magnetic declination in Oregon varies depending on the specific location within the state. However, as a general guideline, it typically ranges between 14 to 16 degrees east. It's important to use updated resources or tools to obtain the most accurate magnetic declination value for a specific location.
An isogonic map shows lines of equal magnetic declination, which is the angle between true north and magnetic north. This information can be used to determine the magnetic variation at different locations on the map.
If you really want accuracy (and the fact that you're even bothering to ask about declination suggests that you do) you should look it up for a particular location, not an entire state.
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.
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.
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.
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.

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.
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.
