The "North" end of a compass needle points to the magnetic North pole in either hemisphere kinda-sorta. Actually, a compass needle more or less orients itself to an imaginary line connectin the planet's 2 magnetic poles, North and South, which happen, BTW, not to be the geographic poles of the planet. Both poles wander some, so the exact lay of the line varies a bit. Tables offering adjustments, or declination offsets, to correct Magnetic Compass North to True North are readily available. Lotsa geomagnetic info - including a nifty interactive declination calculator,HERE
A trivia bit: electromagnetically, the Magnetic North pole actually is a "South" pole, and vice-versa. Don't let that bother you, though - acompass works like a compass just about wherever you are on the planet, with the exception of locations known as magnetic anomalies.
