Magnetic Declination is also referred as the magnetic variation.Magnetic Declination is represented in the Greek word.\(\delta = Magnetic\,Declination\)
Magnetic Declination is associated with the year, longitude and latitude of a given location.
Calculation Of Magnetic Declination Using A Calculator
T = M + V
M = C + D
T = C + V + D (which is a general equation relating compass and true bearings)
C = Compass Bearing
M = Magnetic Bearing
T = True Bearing
V = Variation
D = Compass Deviation
