Its needle is a fine bar-magnet on a low-friction pivot to allow it to align itself with the Earth's magnetic field.
Its North is therefore the Earth's magnetic, not rotational, North Pole, so a correction has to be made to the reading to establish the true geographical bearing. Since the magnetic pole slowly precesses over the years, the correction varies with time.
Yes if you are in the north and south poles your compass will go haywire
No. Being near a magnet (or magnetic field) completely puts off the compass as the compass is influenced by it and will not align with the Earth's natural magnetic field.
First make sure that your compass is flat on your hane/arm/ground also please go to my website- www.toppicks.webs.com
Compasses do not work well in the presence of of electromagnetic fields.

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.
then make a compass
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.
