Maps like these, published by the BGS and NOAA show the magnetic declination, the angle between magnetic and geographic north, at various points on earth, depicted as an isoclinic map of equal inclination value contours.

E.g., along points on the green line, the magnetic inclination is zero, i.e., magnetic north lies in the direction of the geographic north.
