指示方向的工具

AI overview

A compass is a device that shows cardinal directions and helps people navigate and understand where they are geographically. It typically works by using a magnetized needle that points toward magnetic north, though modern compasses may also use gyroscopes, magnetometers, or GPS receivers to determine direction.

指南针，又稱羅盤、司南和指北針，是一种用于指示方向的工具，广泛应用于各種方向判讀，譬如航海、、城市道路、地圖閱讀等领域。指南針又稱指北針，因為當代指向針常在指向北方的一端漆上顏色標記，以便使用者尋找北方。越是靠近兩極地區，指南針就越沒辦法發揮功效：在北極點時，地表上的任何方向都可以被視為南方；在南極點時，地表上的任何方向都可以被視為北方。
