The [[compass]] is a [[magnetometer]] used for [[navigation]] and orientation that shows direction in regards to the [[Cardinal direction|geographic cardinal points]]. The structure of a compass consists of the compass rose, which displays the four main directions on it: [[East]] (E), [[South]] (S), [[West]] (W) and [[North]] (N). The angle increases in the clockwise position. North corresponds to 0°, so east is 90°, south is 180° and west is 270°.
