A compass is a navigational instrument that shows direction relative to the Earth's magnetic poles. It consists of a magnetized needle that can rotate freely, pointing towards the magnetic north. Compasses are essential tools for navigation, helping travelers, hikers, and sailors find their way in unfamiliar areas. The basic design of a compass includes a circular dial marked with cardinal directions: North, East, South, and West. Compasses can be used in various settings, from outdoor adventures to maritime navigation. They are often combined with maps to enhance accuracy and help users determine their location and route.
