The magnetic industry exerts a torque within the needle, pulling the North end or pole of your needle about towards the Earth's North magnetic pole, and pulling the other towards the Earth's South magnetic pole.
These figures enable the compass to show azimuths or bearings which are generally mentioned in levels. If local variation between magnetic north and correct north is understood, then direction of magnetic north also provides direction of true north.
[forty] The resulting legitimate bearing or map bearing may well then be browse with the degree indicator or direction-of-travel (DOT) line, which can be adopted as an azimuth (course) to your vacation spot. If a magnetic north bearing or compass bearing is desired, the compass needs to be modified by the amount of magnetic declination prior to utilizing the bearing to ensure each map and compass are in settlement.[forty] Within the specified illustration, the large mountain in the 2nd Photograph was picked since the target place within the map.
