A compass is a helpful, easy-to-carry tool. Wherever you are on earth, one end of a compass needle will point to the North Pole. It follows a imaginary line that connects to the magnetic poles of earth. Once you direction is north, you can easily determine south, west, and east. For a compass to work properly, its needle must be light-weight and turn easily. The compass cannot be close to a magnet. Otherwise,the needle will respond to the pull of the magnet rather than to Earth's magnetic field.
Another AnswerA compass consists of a lightweight needle (a bar magnet), pivoted, so that it can freely rotate horizontally. The needle aligns itself with the earth's magnetic field, whose direction is from Magnetic South (located in the Antarctic) towards Magnetic North (located in the Arctic). This is because the earth behaves as though there was a large bar magnet, buried deep within the earth, whose north pole is below the Antarctic and whose south pole is below the Arctic (remember, Magnetic North and Magnetic South are locations, not magnetic polarities!).
The terms, 'Magnetic North' and 'Magnetic South', are used to distinguish these locations from 'True North' and 'True South'. Once 'Magnetic North' has been established, you can use then determine 'True North' for the purpose of navigation.
Basically, a magnetised needle on a pivot points towards the magnetic North of the World, based on the attraction of North and South magnets.
The compass is important because with out it we would get lost. It helps ships navigate their way to land, and people that get lost in the woods back to their camp. To sum it up a compass helps you find you way, get your bearings, and navigate.
1. first draw a line any measurements 2. then get your compass and place it on the left side of your line remembering that the compass has to be more than halfway open then go up to the middle with ur compass and draw one half of a cross with the compass then draw another half a cross below the line not changing the width of the compass but make sure it is in line with the other half cross now take the compass of your page now place the point on the other side of the line and do the same as i just said then you should get two crosses one above the line and one below the finishing touch is get a ruler and where the crosses meet draw a line strainght the way down and then your done i hope that helped i learnt it in a maths lesson
Compasses are commonly filled with oil, kerosene, or alcohol.

If your unable to figure out how to work a compass its probably best not to use it.

The compass indicates the direction of magnetic North, from that you can work out South, East, West and all the other points on the compass.
The iPhone's digital compass application works just like any magnetic-needle compass. Launch the application by tapping the "Compass" button on the iPhone's.

the clock is rotating like the sun and that's how a compass works in physical education.

Why not? the desert is just the same as any other place on planet earth. Magnetic compasses work fine in the desert. See the "Where does the magnetic compass not work?" question for some places where they don't work.
Rather than type a long answer - see the related link from Wikipedia for their entry on a gyro-compass.
Iron or steel. Since it is a magnet, a compass will point to iron instead of pointing North.
a compass can be used anywhere.... the accuracy however may suffer in the magnetic polar regions. Then of course there is outer space where a compass would not work
