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. WebClick the map to show data near to the point you clicked.
