What is a magnetic azimuth?

A magnetic azimuth refers to the angular distance measured from magnetic north to a specific line of direction, typically indicated in degrees. This measurement is essential in navigation and orienteering because it helps determine the bearing related to the Earth's magnetic field rather than geographic coordinates. Understanding magnetic azimuth is crucial for accurate navigation and orientation, particularly when using a compass.

The other options represent concepts that are related to navigation and direction but do not accurately define a magnetic azimuth. For example, the angle between true north and geographic features involves geographic bearings rather than magnetic ones, while leveling land pertains to surveying and does not involve angular measurements relevant to direction. The angle difference between grid north and true north is a separate concept known as grid declination, which deals with map reading and the coordinate grid system rather than magnetic orientation.
