For pratical use and scientific research, Belgium must know the value of continuous variations and the geomagnetic field.This is one case for magnetic declination: it is used to find the direction of north with the compass. This is done using the Magnetic Observatories of Dourbes and Manhay. A complete measure of geomagnetic vector is recorded every minute.
