The needle of a compass must be free to rotate so that it can point to magnetic north. The magnetic field of the earth not only rotates the compass needle horizontally but also pulls one end down. If it pulls the needle down it can stop it from turning freely so on many compasses the needle is balanced for use in a specific zone. There are 5 zones. Austraila and Britain are in different zones. This means the needle may not be level if used in the other's zone. Needles are balanced by making one end of the needle longer or by adding weight to one end of the needle.

What is the measure of the declination to the north?
Difference between Compass direction and True north.
What is declination on a map?
Declination on a map refers to the angular difference between true north (the North Pole) and magnetic north (the direction a compass needle points). This difference is important for accurate navigation with a compass, as it allows you to adjust your compass readings to align with the map.
What is The discrepancy between the orientation of a compass and true north known as?
The discrepancy between the orientation of a compass and true north is known as declination. It is caused by the difference between the Earth's magnetic field and its geographic North Pole. To navigate accurately, this declination value needs to be factored in when using a compass for navigation.
True or false Declination is the difference between true north and magnetic north?
True. Declination is the angular difference between true north (the direction of the North Pole) and magnetic north (the direction a compass points towards).
What is the name of the difference of true north and magnetic north?
The difference is referred to as magnetic, or compass, declination.
What is the difference between a copass and a compass rose?
If you mean the difference between a compass and a compass rose: The compass is the complete instrument. The compass rose is the degree wheel printed under the needle.
What is the difference between a navigational compass and a mathematical compass?
A navigational compass shows the way to North. A mathematical compass (actually used in the plural: compasses) allows you to draw circles accurately.
What is the measure of the declination to the north?
Difference between Compass direction and True north.
What is the difference between a compass and a compass rose?
a compass uses magnets to point north, whereas a compass rose is used on a map to direct north, south, east, and west. to my knowledge a compass rose is only used on a map.
What is declination on a map?
Declination on a map refers to the angular difference between true north (the North Pole) and magnetic north (the direction a compass needle points). This difference is important for accurate navigation with a compass, as it allows you to adjust your compass readings to align with the map.
Eisenhower and his men drove the Italians from North Africa True or False?
Eisenhower and his men were not involved in driving the Italians from North Africa. Indian, British and Australian troops actually drove them out in 1940.
Is there a difference between a compass and a hand-held GPS?
Yes of course one is digital and the other is magnetized.
What is The discrepancy between the orientation of a compass and true north known as?
The discrepancy between the orientation of a compass and true north is known as declination. It is caused by the difference between the Earth's magnetic field and its geographic North Pole. To navigate accurately, this declination value needs to be factored in when using a compass for navigation.
Which end of the british compass needle will be weighted?
The northern end of the British compass needle will be weighted because it is attracted to the magnetic North Pole.
What is the differences in degrees between a southern hemisphere and a northern hemisphere compass?
There is a 180-degree difference between a compass in the southern hemisphere and one in the northern hemisphere. This is due to the magnetic field lines of the Earth, which determine the orientation of the compass needle based on the geographic location.
Which end of a British compass needle will be weighted?
north
Does a map show true north?
yes it does and a compass shows magnetic north. this is where declination takes course between the difference of the two
