A magnetic compass is a navigational instrument that shows direction relative to the Earth's magnetic poles. It consists of a magnetized needle that aligns itself with the Earth's magnetic field, pointing towards the magnetic north. This simple device has been used for centuries by sailors, explorers, and travelers to find their way. The compass typically features a circular dial marked with cardinal directions: North, East, South, and West. It is often housed in a protective casing to ensure durability. Despite advancements in technology, the magnetic compass remains a reliable tool for navigation in various environments, including land and sea.
