GEOLOGY

Detailed explanation-1: -Magnetic declination is defined as the angle between magnetic north and true north on the horizontal plane, which is not constant and keeps changing depending upon the position on the earth’s surface and time. The Greek letter is used as the symbol for magnetic declination and is also known as magnetic variation.

Detailed explanation-2: -Magnetic declination is the direction and amount of variation between the Magnetic Pole and True North. The amount and direction of declination depends upon how those two poles align relative to a given point on Earth.

Detailed explanation-3: -Declination is positive when this angle is east of true north and negative when it is west. Magnetic declination changes over time, and with location.

Detailed explanation-4: -At most places on the Earth’s surface, the compass doesn’t point exactly toward geographic north. The deviation of the compass from true north is an angle called “declination” (or “magnetic declination").

Detailed explanation-5: -Updated On: 27-06-2022. The magnetic dip is zero at magnetic equator on the earth suface.
