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.
Deviation in a magnetic compass can be caused by nearby magnetic or electrical equipment on a ship or aircraft, as well as the magnetic properties of the structure itself. Factors such as magnetic fields from engines, wiring, or metal structures can disrupt the Earth's magnetic field and lead to deviation. Calibration and adjustment can help minimize deviation in a compass.

What are the errors of a magnetic compass?
The errors of a magnetic compass include deviation, which is caused by local magnetic fields on the vessel, and variation, which is the difference between true north and magnetic north. Other errors can be caused by inclination, interference from metallic objects, and incorrect calibration. It is important to regularly check and adjust the compass to minimize these errors for accurate navigation.
What characteristic of iron would make it bad for materials for the housing around 2 compass?
Iron is a magnetic material, which could interfere with the functioning of the compass needle by causing deviation from true north. This is known as magnetic interference. To prevent this issue, materials with low magnetic permeability, such as aluminum or non-magnetic stainless steel, are preferred for compass housing.
What will happen if you place a magnetic compass in an electric curcuit?
Placing a magnetic compass in an electric circuit would interfere with its ability to accurately point to the Earth's magnetic north. The magnetic field generated by the electric current in the circuit would cause the compass needle to deflect from its normal orientation.
Why does a compass needle change direction when it is near a magnetic field?
A compass needle is a small magnet that aligns itself with the Earth's magnetic field. When near a stronger magnetic field, like that of a magnet, the compass needle will be influenced by the stronger field and adjust its direction to align with it.
Will a compass always work?
A compass will work as long as it is not near strong magnetic fields or electronic devices that can interfere with its reading. Additionally, in extreme polar regions, the magnetic north and south poles can shift, affecting the accuracy of the compass.
Will titanium effect a magnetic compass?
Yes, titanium is non-magnetic and does not affect the accuracy of a magnetic compass. The compass will still function normally near titanium objects.
Why deviation card of magnetic compass made on north hemisphere not suitable for south hemisphere?
The deviation card of a magnetic compass is specific to the location and magnetic conditions where it was calibrated. Deviation values change when crossing the magnetic equator due to differences in magnetic variation between the two hemispheres. Therefore, a deviation card calibrated in the northern hemisphere may not accurately represent the deviations experienced in the southern hemisphere.
List the cause and effect connections between the Chinese invation of the Magnetic compass and Zheng He's voyage?
The cause is the Chinese invention of the magnetic compass. The effect is the voyage of Zheng He. The invention of the magnetic compass allowed Zheng He to make his voyage.

Different magnetic deviation and magnetic variation?
Magnetic deviation is the error caused by the internal magnetic fields of a ship or aircraft, while magnetic variation is the difference between magnetic north and true north at a specific location. Deviation can be corrected by installing compensating magnets on a vessel, while variation requires adjustment in navigation calculations.
What will happen if you place a magnetic compass in an electric curcuit?
Placing a magnetic compass in an electric circuit would interfere with its ability to accurately point to the Earth's magnetic north. The magnetic field generated by the electric current in the circuit would cause the compass needle to deflect from its normal orientation.
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 is compass error?
Compass error refers to the difference between the actual magnetic heading of a compass and the heading it indicates. It can be caused by various factors such as magnetic interference from the ship or aircraft it is installed on, deviation due to metal objects nearby, or variation caused by the difference between true north and magnetic north. Compass error needs to be regularly assessed and corrected to ensure accurate navigation.
Why does a compass needle change direction when it is near a magnetic field?
A compass needle is a small magnet that aligns itself with the Earth's magnetic field. When near a stronger magnetic field, like that of a magnet, the compass needle will be influenced by the stronger field and adjust its direction to align with it.
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.
Will a compass always work?
A compass will work as long as it is not near strong magnetic fields or electronic devices that can interfere with its reading. Additionally, in extreme polar regions, the magnetic north and south poles can shift, affecting the accuracy of the compass.
