Magnetic Compass

A magnetic compass is a navigation tool used to determine direction based on the Earth's magnetic field. It consists of a magnetized needle mounted on a pivot, which aligns itself with the Earth's magnetic field to point towards the magnetic north pole.Magnetic compasses have been used for navigation for centuries, and are still widely used today in various applications such as marine navigation, aviation, and hiking. The compass needle is usually mounted in a housing that contains a numbered dial or compass rose, which allows the user to read the direction indicated by the compass.
