As one moves away from the magnetic North Pole, its distance to the geographical pole becomes increasingly irrelevant for magnetic declination. Local disturbances and attempting to use a model beyond its valid date range could cause greater errors. Accuracies for the force components (Horizontal - H, North - X, East - Y, Vertical - Z, and Total force - F) are generally within 100 to 250 nanotesla. Solar and lunar eclipses, why they occur, when the next eclipse is, and from where you can see them. Magnetic declination, in a few words, refers to the disparity that exists between True North and Magnetic North - or, if you prefer, the angular deviation between the real, geographical north and the north pointed towards by the magnetic needle in our compass.
