Compasses are mainly used in navigation to find direction on the earth. This works because the earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the earth’s magnetic field direction and points north-south.
How Is a Compass Used?
A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions, or “points”. A compass is a navigational tool that is used to determine the direction of a journey, either on land or sea. It is one of the oldest navigational instruments and is still used today by people all over the world.
Compasses consist of two main parts: a needle and a base plate. The needle is usually made of magnets and is balanced on a pivot point. The north end of the needle is attracted to the Earth’s magnetic field and points in the direction of magnetic north. The base plate is a flat, transparent disk that is marked with directions, angles, or bearings.
Compasses are used to determine direction in a variety of different ways. They can be used to help find a person’s way in the wilderness or to help guide a boat. The most common use of a compass is to orient oneself to a map. By placing the compass on the map, one can make sure that they are heading in the right direction based on the map’s orientation.
Compasses are also used to measure distances between two points. By using the compass to align two points, one can
