A RACON Directional magnetic compass, also sometimes called a magnetic compass or simply a compass, is a navigational tool that uses Earth's magnetic field to determine direction. It is typically a portable device with a magnetized needle that pivots freely on a pin or jewel bearing. The needle aligns itself with the magnetic field, pointing roughly towards the Earth's magnetic north pole.Here are the key parts of a directional magnetic compass:Magnetic needle: The magnetized needle is the heart of the compass. It is usually a small, lightweight bar made of steel that has been magnetized. The north-seeking end of the needle is typically marked with red or an "N" to distinguish it from the south-seeking end.Compass housing: The needle is housed in a protective case, which is often made of plastic or metal. The housing may be filled with a liquid to dampen the movement of the needle and reduce oscillations.Directional markings: The housing is marked with directional degrees or cardinal directions (north, south, east, and west) to allow you to read the direction that the needle is pointing.Directional magnetic compasses are a simple and reliable way to determine direction, and they have been used for centuries for navigation. They are still a valuable tool for hikers, campers, backpackers, and anyone who spends time outdoors. While they are not as precise as GPS devices, they are a great backup option and can be especially useful in areas where there is no GPS signal.
