![]() As a traveller cruises the east coast of the United States, for example, the declination varies from 16 degrees west in Maine, to 6 in Florida, to 0 degrees in Louisiana, to 4 degrees east in Texas. Magnetic declination varies both from place to place and with the passage of time. Magnetic declination should not be confused with magnetic inclination, also known as magnetic dip, which is the angle that the Earth's magnetic field lines make with the downward side of the horizontal plane.ĭeclination change over time and location The term magnetic deviation is sometimes used loosely to mean the same as magnetic declination, but more correctly it refers to the error in a compass reading induced by nearby metallic objects, such as iron on board a ship or aircraft. The lowercase Greek letter δ (delta) is frequently used as the symbol for magnetic declination. Isogonic lines are lines on the Earth's surface along which the declination has the same constant value, and lines along which the declination is zero are called agonic lines. The angle between magnetic and grid meridians is called grid magnetic angle, grid variation, or grivation." īy convention, declination is positive when magnetic north is east of true north, and negative when it is to the west. ![]() Somewhat more formally, Bowditch defines variation as "the angle between the magnetic and geographic meridians at any place, expressed in degrees and minutes east or west to indicate the direction of magnetic north from true north. This angle varies depending on position on the Earth's surface and changes over time. Magnetic declination, or magnetic variation, is the angle on the horizontal plane between magnetic north (the direction the north end of a magnetized compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole). N g is geographic or true north, N m is magnetic north, and δ is magnetic declination. Apart from this Real States & Healthcare Industries.In addition, we also serveGulf Countries Like Doha- Qatar, South Africa (Uganda), Australia.Angle on the horizontal plane between magnetic north and true north Example of magnetic declination showing a compass needle with a "positive" (or "easterly") variation from geographic north.
