What does a one-sided arrow typically represent in navigation?

In navigation, a one-sided arrow is typically used to represent magnetic north. This arrow communicates the direction in which a compass needle will point, which is influenced by the Earth's magnetic field. It is essential for navigational purposes, especially when using a magnetic compass, as the direction indicated by the one-sided arrow can help navigators align their path and make accurate course adjustments.

True north, grid north, and directions such as east are represented differently in navigational contexts. True north refers to the geographic North Pole, and grid north pertains to the north direction according to a map grid, often indicated by specific lines or symbols on maps. East direction is indicated as a cardinal point on compasses but is not specifically represented by a one-sided arrow in navigation. Understanding magnetic north and how it is depicted is crucial for accurate navigation and orientation in various environments.
