The magnetic declination for Houston, TX is approximately +2 degrees. This means that magnetic north is currently about 2 degrees east of true north in that location.
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.
