A compass is a navigational tool that consists of a magnetic needle or a magnetized card, which aligns itself with the Earth's magnetic field. It is typically housed in a circular case and marked with cardinal directions (north, south, east, and west) as well as intermediate points. By using a compass, one can determine their direction and navigate accurately, making it an essential instrument for travelers, hikers, sailors, and explorers. The symbol "🧭" represents a compass and is often used to signify navigation, exploration, and finding one's way.
