Declination map north america
WebThe difference between magnetic north and true north is “magnetic declination.” In the continental U.S., declination can vary from nearly 20 degrees east in places on the West Coast to nearly 20 degrees west in … WebHistorical Magnetic Declination. description: Magnetic declination is an important concept for accurate navigation. A compass will always point along the lines of magnetic force (which converge on what are called the magnetic poles). The angle between the direction of force and the direction of the geographic north pole is called the declination.
