Because the vertical soft iron changes polarity as the ship moves from one hemisphere to another the deviation recorded in one hemisphere will change

Why does the compass point north in the southern hemisphere?
The direction of magnetic flux or lines of force is from north polarity to south polarity, and a compass needle will always align with that direction, wherever it is used. Since the magnetic polarity of the location we call Magnetic North is a south, a compass needle will point in that direction.
What instrument is used for determining direction?
A compass. The North magnetic pole is in the direction of the N on the compass. Therefore, the North magnetic pole is in fact a magnetic field south pole since it *attracts* the north magnetic field pole of the compass magnet.
When In the Northern Hemisphere a magnetic compass will normally indicate a turn toward the north if?
an aircraft is accelerated while on an east or west heading.
Does the compass needle point in the same direction indicated by the magnetic field maximum?
Your compass needle will align itself with the lines of magnetic force at your location. This will diverge from the simple 'earth monopole model' depending on the local magnetic field, and any local geomagnetic anomalies.On most topographic maps, the 'magnetic deviation' and its annual variance will be marked on the map legend. Where i am it is about 25 degrees east of the true magnetic north.
Why do orienteering maps have magnetic North Pole instead of the true North Pole?
That is because the map is used with a magnetic compass. Since the needle on the compass points in the direction of magnetic north it is easier to use the map with the compass if the lines drawn on the map indicate magnetic north.
Will titanium effect a magnetic compass?
Yes, it is commonly known as magnetic deviation
What cause deviation in a magnetic compass?
The compass needle will only align itself with the magnetic meridian if it is free from all other influences except the magnetic field of earth.This is rarely so, particularly on a ship which constructed on steel. The magnetism induced in the steel by the earths magnetic field causes the compass needle to deviate from the magnetic meridian, by an amount which is called the DEVIATION.
Different magnetic deviation and magnetic variation?
In relation to aviation... Deviation is the difference between a true heading and the compass heading. The compass heading is different from true due to magnetic fields induced by the components of the aircraft. Variation is the difference (angle) between True North and Magnetic North. Variation changes depending on your position and is normally indicated on maps as a dashed line with the variation in degrees along that particular line.
Why does the compass point north in the southern hemisphere?
The direction of magnetic flux or lines of force is from north polarity to south polarity, and a compass needle will always align with that direction, wherever it is used. Since the magnetic polarity of the location we call Magnetic North is a south, a compass needle will point in that direction.
How do you know that the compass point at north always?
Because of the Magnetic North Pole, a point on the Earth's Northern Hemisphere
When In the Northern Hemisphere if an aircraft is accelerated or decelerated the magnetic compass will normally indicate?
correctly when on a north or south heading.
Why does a compass needle change direction when it is near a magnetic field?
Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.
What In the Northern Hemisphere the magnetic compass will normally indicate a turn toward the south when?
the aircraft is decelerated while on a west heading.
Is gyrosyn compass a combination of magnetic compass and artificial horizon?
No,a Gyrosyn compass is a combination of a Magnetic compass and Direct reading compass.
What instrument is used for determining direction?
A compass. The North magnetic pole is in the direction of the N on the compass. Therefore, the North magnetic pole is in fact a magnetic field south pole since it *attracts* the north magnetic field pole of the compass magnet.
What does a dip compass do?
A compass does not point to the North Pole, it aligns itself with the lines of magnetic force at your location. In the Northern Hemisphere you are closer to the North Pole, so the strength from that direction is greater, and the compass "points north". In the Southern Hemisphere, similarly, the magnetic South Pole is closer, and the other end of the compass points to the south Pole. So far so good. But when you are close to either pole, the magnetic field dips into the earth - steeply at the Poles themselves. [Ordinary compasses are counterbalanced a little so the compass needle or card is approximately horizontal. The compass manufacturers divide the earth into five 'balance' zones.] So a dip compass is suspended between two pivots, and will indicate the steepness of the magnetic fields dip. It differs from an ordinary compass.
Why is the magnetic compass so important?
