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.

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.

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 a magnetic compasses natural tendencies to produce erroneous readings in certain circumstances. Sometimes this may be due to environmental effects such as proximity to a strong magnetic field. Compass error is also frequently the result of shortcomings or anomalies in the way compasses work. Compass error due to environmental effects usually refers to an airplanes compass being drawn toward the magnetic fields generated by the aircrafts engines. This is called magnetic deviation. Additionally in some regions with high concentrations of iron in the soil, compasses may give all sorts of erroneous information. Magnetic compass "variation" deals with the difference between the magnetic north pole (which magnetic compasses point to) and the true north pole (the actual geographical north pole.) While this difference may seem minor, magnetic variation can mean a difference of up to 4 or 5 degrees in some places. In aviation, compasses may also give erroneous readings when turning or performing other maneuvers. This is due to the curvature of the earth combined with the fact that the compass needle wishes to point at the magnetic north pole. Since the earth is round, and the compass points to the magnetic north pole, the compass needle will in most cases be drawn to a point below the horizon from the users standpoint. This will cause the magnetic compass to precede when turning to a northern heading, and to lag when turning to a southern heading.

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.
