Compass - Page 13

A compass is a navigational instrument that shows direction relative to the Earth's magnetic poles. It typically consists of a magnetic needle that aligns itself with the Earth's magnetic field, indicating the cardinal directions: north, south, east, and west. The compass is commonly enclosed in a housing, often with a rotating dial that displays these directions for easier reading. Compasses are used in various fields, including outdoor activities like hiking and sailing, as well as in geography and cartography to assist with navigation and orientation. The fundamental principle behind a compass is its ability to detect magnetic north, allowing users to determine their bearings and navigate accordingly.
