What's the problem, exactly?

Did you calibrate the compass http://support.apple.com/kb/TS2767
I don't know if the iPad's compass naturally shows true or magnetic
north; depending on where on earth you are, a compass can point quite far off true north.

The problem is that the compass shows a bad north (error is 180 degrees!) when the iPad is rotated to a certain angle. Yes Ic alibrated it

Then you should probably contact Apple about it:

So? Contact them another way that works for you. Or are you actually
trying to suggest that someone living outside the USA has no way of
contacting Apple?

Thanks but I was curious to know if it is a general defect or relate only to my device.

Nope. Mine works fine. Through it seems to be easier distracted than the compasses in my 3GS iPhones. Did you try getting away from electric equipment and or heaps of metal?

Also, what do you mean by "turn"? your description is a little
ambiguous.

In any case, your iPad is still under warranty and if the compass
doesn't work for you, apple will exchange it.

That article's pretty useless. What does it mean "move it in
a figure 8"? It doesn't seem to do anything anyway.

move the phone as if to draw an 8 in the air.

I suspect it's working as design for the original poster, but as you said, it seems to be much more easily distracted.

I've got a 3GS and a iPad 3G, I wouldn't trust either of their compasses over my rough sense of direction; I'm not exactly what you'd call an outdoorsman, although I can navigate Vegas hotels reasonably well, so read what you want into my internal compass.

Anyway, I had the opportunity to try it today, I was stuck in a relatively unfamiliar part of downtown today in a reasonably small city; not an urban canyon, I was in a large park near a lake at the time and due to a triathlon in the area the route I'd normally take was blocked so I pulled out my 3GS and fired up Google Maps to figure out a better route and tried the compass to figure out which of a couple streets at different angles would be better (in other words, I was trying to figure out which was which)

It never did get the direction right in the ~12 minute walk to my destination, usually it was 30-45 degrees off but randomly swung wildly with the phone being held flat.

Holding it vertically was noticeably better, but when I'd hit a corner and turn it would usually get lost again for some time. I also looked much dorkier holding the phone vertically while walking around so I didn't do this for long, mostly when I was stopped waiting for a crosswalk light.

Comparing the 3GS to the iPad in every situation where I've tried both together, mostly while navigating in a car, the 3GS has been better than the iPad, but neither compass is reliable enough to give more than a rough indication of direction when compared with the surroundings.

With all of that being said, I'd rely on MotionX's virtual compass (based on the direction you're moving) over the native 3GS compass any day, and I wouldn't miss either the 3GS or iPad's compass if it broke.

Honestly though I think it's just a limitation of digital compasses, especially at the scale that is needed for integration into an iPhone.

Well, yes. But is the orientation of the phone supposed to stay the
same, or change, as you do that? Either way, it's never seemed to
make any difference.

I get the impression the orientation would stay relatively the same unless you tried really hard to twirl the phone while you did it, or spun around like a dancer. : P

iPhone rather than iPad, but yes.
