Of True North and Magnetic North and Compass North which way is really up?
True North is the real North, following along the lines of longitude which converge at the North Pole, the farthest geographically North point on the planet, and the rotational axis of the planet. Magnetic North and Compass North are both the same thing, with the compass pointing along Magnetic North. Magnetic North however, is not the real North. If you were to follow your compass as far North as it could point, you would end up on the Prince of Wales Island in the Northwest Territories of Canada, over 1,500 miles away from the North Pole. Magnetic North can be adjusted to True North on your compass by knowing the local magnetic variation of your area and adding/subtracting accordingly. A third North is Grid North, which follows the Grid Lines on a standard map. At the South Pole, every direction is True North, so Grid North is used instead and can be found by following the Prime Meridian northwards. Hope that helps.
Asked in Geophysics, Magnetism
How can you find out which is the north-seeking and the south-seeking pole of a magnet?
Stand somewhere where you know which way is north (get a map, find yourself on it, face a landmark which is about north (or south) which is marked on the map) The north seeking pole will be the one facing the same way as you. Alternately you can find a magnet marked with N and S and use that. >>>>>>>>>>>>>>>>>>> This is sadly half an answer. If you stand with a magnetic compass on the ground (assuming no other interference) then yes, you should be able to determine magnetic north. However maps are (in the most part) aligned to True North....which is not always the same as magnetic north. In the UK it's different by up to 10 degrees off. Go to South Africa/Madagascar and you're talking 20-30 degrees off. All this has to do with the fact that the magnetic and north poles are not in the same location - in fact they are just under 600 miles apart and change as the years go by. If you stand on the ground with a map aligned to true north however AND know the variation (that is the difference in degrees between true and magnetic north) then yes, you should be able to point to both with a bit of maths! Better Answer Use a compass. It's needle will point to the magnet's south pole.

Asked in Time
How do you find north by using your wrist watch?
Set your watch to accurate local time (no daylight saving), hold it flat, point the 12 on the dial to the Sun, and at Noon it will always point to North (but in the Northern hemisphere it will point to South). At other times, some teach that North can always be found by pointing the hour hand to the sun, and that North is then half-way between the hour hand and the 12, but this is not recommended at all by Harold Gatty, one of the world's great navigators, in his book "Nature is Your Guide" as this variation is not accurate: use this variation at your own risk.
