As of October 2023, the magnetic declination for Cincinnati, Ohio, is approximately 6 degrees west. This means that magnetic north is about 6 degrees west of true north in that area. However, magnetic declination can change over time due to shifts in the Earth's magnetic field, so it's advisable to check for the most current information before navigation.
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.
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.
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.
Magnetic declination is typically worst in areas close to the magnetic poles, particularly near the North and South Poles, where the magnetic field lines are more vertical and can cause significant variations in compass readings. Additionally, regions with complex geological formations or near large magnetic anomalies can also exhibit significant declination variations. Graphically, this can be represented on maps where declination angles deviate sharply from zero, indicating considerable differences between true north and magnetic north.
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.
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.

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.
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.
The magnetic declination in Yosemite Valley typically varies between 10 to 15 degrees east, depending on the specific location and the time of year. This angle indicates the difference between true north and magnetic north. For the most accurate and current declination, it's advisable to consult a local magnetic declination map or a reliable online resource, as it can change over time.
