The sum of variation and deviation. The angle of magnetic declination, or magnetic variation, is the angle between the local magnetic field lines with which a magnetic compass needle lines up and the direction of true north, the north axis point of Earth. In the U.S., that angle varies between 0 degrees and about 20 degrees and also varies over time.
The difference between "true" north and "magnetic" north is called "magnetic variation", which is often abbreviated as "mag var".
The north magnetic pole is in northern Canada, but is continually (although slowly) moving. Topographical or navigational maps are generally overprinted with "mag var" lines and the amount of correction.
Magnetic declination
No. The compass needle points toward the magnetic north pole.
The magnetic poles of a compass needle are named after the directions in which they point. 'Magnetic North' and 'Magnetic South' are LOCATIONS (used to distinguish them from 'True North' and 'Magnetic North'), and do NOT describe their magnetic polarities. As 'unlike poles attract', the north pole of the compass needle points towards Magnetic North, whose polarity must, therefore, be south. By extension, the polarity of Magnetic South is north.
The compass needle is magnetic so has a north pole and a south pole. North attracts north and south attracts south so the compass needle points to the north pole (you could say it - the other end- points to the south pole too).
The direction of the needle will remain unchanged. This is due to magnetic forces, the needle will remain in line with the lines of magnetic force which flow between the north and south poles.
Magnetic declination
No. The compass needle points toward the magnetic north pole.
A compass needle points to the magnetic poles, which are not the same as the geographic poles. There is nothing special about the magnetic field at the geographic poles.
A compass.
It points to true north.
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
It points to true north.
The needle of a compass points towards the Earth's magnetic North Pole.
You need to determine the geographic north, for example by observing sunrise and sunset; by observing the stars; or by using a compass that reacts to Earth's rotation (a gyrocompass). Then you observe where the needle of a magnetic compass points. Finally, you measure the angular difference between the two.
No, a compass points to magnetic north, which may not align perfectly with geographic north in certain locations due to variations in the Earth's magnetic field.
