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.

Will a compass always work?

No. I assume you mean a magnetic compass. A magnetic compass reacts to magnetic fields; the magnetic south pole of Earth is not exactly at the geographic north pole, so at some points of the Earth's surface, the magnetic compass will actually point south instead of north. Also, a magnetic compass will be influenced by other magnetic fields, e.g., current-carrying wires.No. I assume you mean a magnetic compass.

How does a compass needle respond when a compass is Place with in a magnetic field?

If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions


What are the problems of using a magnetic compass at sea?

A magnetic compass can be influenced by surrounding metal. For instance, take a compass bearing when your pocket knife is in your breast pocket, too close to the compass, or there is an underground metal water pipe near by, may cause an error in your compass reading. Even magnetic (iron) rocks you are standing on, can cause a wrong reading. When taking a magnetic bearing, leave your metal framed rucksack to one side.

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.

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.

Why deviation card of magnetic compass made on north hemisphere not suitable for south hemisphere?

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


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.
