The declination diagram
A magnetic compass has a needle mounted in a way that allows it to turn freely. Tis needle always lines up with Earth's magnetic field and points toward magnetic north. The needle is set over a diagram that shows east,south, and west. By knowing which way is north, a sailor can find the other diections.

Equal to the G-M angle
displayed on a nautical chart that shows the amount and direction of the magnetic declination for a specific location. It is used by navigators to correct compass readings and determine true north.
If west declination(ie: magnetic to left of grid)_formula= GN>>>MN You add MN>>>GN You subtract. Just the opposite if on the other side(East declination)

There can only be one Cartesian North.
its not why its just A diagram of a compass showing direction.
