map) and magnetic north (on your compass). This is called magnetic variation and your map will tell you how many degrees to add to your bearing. This can vary depending on where you are in the country. Step 5 To head in the right direction, you must now re-orientate your compass. This means turning the whole compass around until the magnetic north needle points in the same direction as the

Therefore 3 degrees is the magnetic variation. Maps are oriented to Grid North and not Magnetic North - and the difference between the two is usually shown in the map margin. You'll need to allow for this difference when converting between a map bearing (based on Grid North) and a Compass bearing (based on Magnetic North).

Magnetic Declination & Grid Convergence

The first is magnetic declination or variation—the angular difference between magnetic North (the local direction of the Earth's magnetic field) and true North. The second is magnetic deviation —the angular difference between magnetic North and the compass needle due to nearby sources of interference such as magnetically permeable bodies, or other magnetic fields within the field of influence.

The magnetic declination is indicated on the map, with the obligatory indication of the measurement year and the average annual change. To switch to the real course, we first obtain the magnetic course and then add the magnetic declination to the east or subtracted the one to the west. Then the average annual change of the magnetic declination is taken into account (it's multiplied by the
