The angle between the plane of the magnetic meridian (the needle of a magnetic compass will lie in this plane) and the plane of the geographical meridian at this point of the earth’s surface is called the magnetic declination. The meridian through Greenwich, England, also called the Prime Meridian was set at zero degrees of longitude, with other meridians being defined by the angle at the center of the earth between where it and the prime meridian cross the equator. It is considered easterly or ( + ), when the magnetic north is eastward of geographic meridian. Planes which contain the rotation axis intersect the surface at the meridians; and the angle between any one meridian plane and that through Greenwich (the Prime Meridian) defines the longitude: meridians are lines of constant longitude. What is the angle of declination and the angle of dip at a place? Parallel to the earth’s surface at equator. The magnetic meridian is an equivalent imaginary line connecting the magnetic south and north poles and can be taken as the horizontal component of magnetic force lines along the surface of the earth. (i) Magnetic declination: Angle between the magnetic axis and geographical axis y. Alternatively: Angle between magnetic meridian and geographical meridian (ii) Angle of dip : It is the angle which the magnetic needle makes with the horizontal in the magnetic meridian.. Alternatively : The angle which the total magnetic field of the earth makes with the surface of the earth. 1. Meridians (lines running from pole to pole) connect points with the same longitude. Geographical meridian 6. However, a compass needle will not be steady in the magnetic meridian, because of the longitude from east to west being complete geodesic. 1. MAGNETIC VARIATION changes with a change. at a given place it is the angle between the geographical north south direction and the direcation indicated by a agnetic compass needle in its equillibrium. The angle between the magnetic meridian and the geographic meridian at a place is called the declination or variation at that place. The angle between the geographic meridian and the magnetic meridian, is called variation at that location & is available from the compass rose printed on the chart. The angle that the horizontal element of the flux vector makes with the geographic north is that the angle of magnetic variation or just declination. Keep in mind that when you are located west of the 0° line-of-declination, the declination is east (or positive).
