Does a compass point north in the Southern Hemisphere?

One end points north, and the other end will point south. Simple, isn't it.

No, the needle in a compass is a magnet, with the south pole of the magnetic needle painted as "North". This is because opposites attract, so, that end of the needle will go towards the north pole of the Earth. Even if you are in the southern hemisphere, the magnetic needle in the compass will still behave the same way, so it will still point to north. Hope this clears it up for you.

Yes. The North on a compass points to magnetic north (admittedly you would have a problem at the magnetic south pole as north is pretty much in every direction).

A compass always points to magnetic north no matter where your at.

Yep, it does.
