A compass is a device that displays the cardinal directions utilized for navigation and geographic orientation. It normally consists of a magnetized needle or other factor, like a compass card or compass rose, that may pivot to align alone with magnetic north. Other techniques can be used, which include gyroscopes, magnetometers, and GPS receivers.
Some compasses characteristic a special needle balancing process that can properly reveal magnetic north regardless of the distinct magnetic zone. Other magnetic compasses have a small sliding counterweight mounted within the needle.

The difference between legitimate north and magnetic north in a certain location is calculated by an angle named what?
This discovery was presumably rapidly accompanied by a second, that an iron or steel needle touched by a lodestone for very long enough also has a tendency to align alone within a north-south course. With the knowledge of which way is north, naturally, another path are available.
