Azimuth relative to magnetic north.



Related Terms

ELECTROMAGNETIC INDUCTION

The production of electromotive force (EMF) in a conductor through relative motion of a conductor and a magnetic field, or by the change in the strength of magnetic flux around the conductor.

RELATIVE AZIMUTH

Azimuth relative to heading.

COMPASS DECLINOMETER

An instrument used for magnetic distribution surveys; employs a thin compass needle 6 inches (15 centimeters) long, supported on a sapphire bearing and steel pivot of high quality; peep sights serve for aligning the compass box on an azimuth mark.

TRUE AZIMUTH

Azimuth relative to true north.

FALSE RELATIVE MOTION

False indications of the movement of a target relative to own ship on a radar display that is unstabilized in azimuth due to continuous reorientation of the display as own ship's heading changes.

COMPASS AZIMUTH

Azimuth relative to compass north

MAGNETIC HEADING

Heading relative to magnetic north; compass heading corrected for deviation.

VIBRATING NEEDLE

A magnetic needle used in compass adjustment to find the relative intensity of the horizontal components of the earth’s magnetic field and the magnetic field at the compass location. Also called HORIZONTAL FORCE INSTRUMENT.

MAGNETIC AMPLITUDE

Amplitude relative to magnetic east or west.

NORTH

The primary reference direction relative to the earth; the direction indicated by 000° in any system other than relative. True north is the direction of the north geographical pole; magnetic north the direction north as determined by the earth’s magnetic compass; grid north an arbitrary reference direction used with grid navigation.
