STRUCTURE:-

A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions (or points). Usually, a diagram called a compass rose shows the directions north, south, east, and west on the compass face as abbreviated initials. When the compass is used, the rose can be aligned with the corresponding geographic directions; for example, the "N" mark on the rose points northward. Compasses often display markings for angles in degrees in addition to (or sometimes instead of) the rose. North corresponds to 0°, and the angles increase clockwise, so east is 90° degrees, south is 180°, and west is 270°. These numbers allow the compass to show azimuths or bearings, which are commonly stated in this notation.

Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the ChineseHan Dynasty (since c. 206 BC),[1][2] and later adopted for navigation by the Song DynastyChinese during the 11th century.[3][4][5] The first usage of a compass recorded in Western Europe and the Islamic world occurred around 1190.
