A good map will have both marked, it will also have "grid north" marked, which may not match either. In the UK grid north is simply the line parallel to the central meridian (2° W), so the further away from there you go, the further it is from true north.

WebFeb 9, 2024 · 4. All charts are drawn in reference to true north, and arrows or isogonic lines (depending on the type of chart) show how to convert that to magnetic. The reason is that true north doesn’t change over time, but magnetic north does. If charts were drawn to magnetic north, they’d have to reframe every chart every few years as the variation ... WebWhen a navaid is first constructed, the antenna is physically oriented to True North. Then a potentiometer adjustment is made to slave the navaid with Magnetic North. This action matches the isogonic line making it agree with a magnetic compass.
WebMagnetic declination, or magnetic variation, is the angle on the horizontal plane between magnetic north (the direction the north end of a magnetized compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole ).
