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

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.
no because of the magnetic field.
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

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.
No, he used one and the world in general was much more advanced than that in 1492. Nor did they think the world was flat.
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.
Though it would be much easier to use a modern-day compass, you could use an ancient Chinese compass if you have a working one. Most compasses from ancient China would have had to be well preserved to work. Maybe it does work, but it would probably be inaccurate because of it's age. If it is in complete working order (you could probably go to a well reviewed pawn shop to tell if it works or is accurate) then yes, you could still use it. Not many people do, though. You could buy some that supposedly work on E-Bay for $700. YIKES!
