The introductory figure summarizes our model for a photoreceptor-based magnetic compass in birds. The geomagnetic field can affect radical-pair reaction yields as governed by the stochastic Liouville equation depicted in the thinking bubble of the bird. These effects result in a modulation of visual information as shown in the right figure. The changes of visual modulation patterns with different orientations of the bird can explain the magnetic compass orientation observed in behavioral experiments.
The Golden Compass.
If your unable to figure out how to work a compass its probably best not to use it.
Because he portable sundial does not work without a compass

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 transforming animals in "The Golden Compass" are called daemons. They are physical manifestations of a person's soul and take the form of an animal that reflects the individual's personality and characteristics.
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.
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
