What do you mean by agonic line?
: an imaginary line on the earth’s surface connecting the north and south magnetic poles and passing through those points where there is no magnetic declination and where a freely suspended magnetic needle indicates true north — compare aclinic line, isogonic line.
What is Isogonic and Agonic lines?
An isogonic line is a line over the surface of the earth upon which magnetic declination is constant. An agonic line is an isogonic line upon which the declination is zero.
What is an agonic line aviation?
Agonic Line. A line drawn on an aeronautical chart along which there is no angular difference between the magnetic and geographic north poles.
What does Agonic mean?
: not forming an angle.
Where is Agonic line?
The line through all points on the earth’s surface at which the magnetic declination is zero; that is, the locus of all points at which magnetic north and true north coincide.
What are Isoclinic and Isogonic line?
Isoclinic lines: A line on a map connecting points of equal dips in the earth’s magnetic field. Isogonic lines: The lines traced on the surface of the globe, or upon a chart, connecting places at which the deviation of the magnetic needle from the meridian or true north is the same.
What are Isoclinic and Isogonic lines?
Where is the Agonic line in the US?
This line is known as the Agonic Line, and the line is also moving. In the year 1900, the Agonic Line passed roughly through Detroit and then was East of Florida. It currently passes roughly west of Chicago and through New Orleans.
What is an Isogonal line?
: an imaginary line or a line on a map joining points on the earth’s surface at which the magnetic declination is the same. — called also isogonal.
