True. Declination is the angular difference between true north (the direction of the North Pole) and magnetic north (the direction a compass points towards).
Magnetic variation is measured using a magnetic compass that indicates the angular difference between magnetic north and true north at a specific location on the Earth's surface. The variation is typically expressed in degrees east or west. Land navigation charts and maps often provide information on the expected magnetic variation for a given area.
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.
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.
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.
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.
There can only be one Cartesian North.
Declination on a map refers to the angular difference between true north (the North Pole) and magnetic north (the direction a compass needle points). This difference is important for accurate navigation with a compass, as it allows you to adjust your compass readings to align with the map.
