Without  using  compass and star constellation how could  i detect that im already in the  north direction ?

Well the simplest way has already been said... the sun rises in the east and sets in the west... so you can work out north from that.... \n\nBut as you mention the stars are we to assume you are trying to find direction at night?\n\nAgain there are many country ways - like the moss growing on trees and prevailing winds etc - but I personally wouldn't rely on this.\n\nSilly thought but if you have a map and can see any landmark or town lit up at night you can get your direction.

If your on one of the poles the needle will keep pointing in the direction of north, but if your on magnetic north the needle will just start spinning around the place.

I bought a field guide that helps you find things with your telescope and basic telescope knowledge. i know you have to know where north/south (which ever is closer to you) and what your latitude is in degrees (how far you are from the equator).

google earth, will show you anyplace around the world.yes it's free and to can rotate and do whatever.

The compass is 360 degrees all around the circle.  315 would be northwest.  A wind out of 315 would be a wind out of the northwest, and would make a vane point in that direction, northwest.

(1) Subtitute the damn values for what you have.\n\n(2) Sin theta=opp/hyps,\n    Tan   "  =opp/adj,\n    Cos   "  =adj/hyps.\n\nNow usually a blind man follows his stick now you might know where you are at the moment - get it???

Same direction as the Sun and the Moon, to the west.\n\n---Addition----\nChristina has a good point. If you were close to one of the poles, the stars would be just turning around and you could not tell if it is west or east direction.

True north would be a line from your position to the geographic north pole.\n\nMagnetic north is a line between your position and the northern magnetic pole.  \n\nSince the northern magnetic pole does NOT coincide with the geographic north pole (IIRC, it is somewhere in northern Canada), there is a difference between those two lines.  The magnitude of that difference depends on precisely where on the earth you are standing when you take your measurement.\n\nThat's why, on all good topographic maps, they have an indicator of both magnetic north and true north, so you can apply the appropriate correction to navigate with a compass.  Of course, global positioning systems are making that problem a non-issue (if you can "see" the satellites . . .).

This question has been adequately answered, but it is a trick question in that every direction at the north pole is south (you can't walk east, west, or north of the north pole), and every direction at the south pole is north. You could, however take one step south, turn and walk east, but you would have to walk in a little circle to maintain your easterly direction. Weird, huh?

a compass tells you which way is north. once you know where north is you can tell in which directions south, east, and west is.

bring the magnets close to each other. If u feel any repulsion, that means u have tried joining opposite poles.\nWith this test u just come to know of the repulsive and attractive sides relative to a magnet. No qualitative nalysis of which is North pole and which is south cannot be done! But hey! If the bar magnet is painted red on one side, then that would be the north pole!

I think you would find a Mercator projection of the map. It shows true direction even if the shape of the land mass is distorted.

You'd need either the OFFICIAL name/designation of the star, or its celestial coordinates (right ascension and declination). Even then, you may have picked a star that's never been catalogued and there'd be no data on it. If you do have the star's celestial coordinates, try this website --> http://www.telescope.org/\n\nThe website gives free access to their telescope so that users can remotely photograph celestial objects they're interested in.

have u heard about right Ascension and declination?\nthose are used 4 finding stars.right asection is measured in hours and declination is measured in degrees.\nu must know abt meridian 2 find stars.It is an imaginary curve that passes across head 2 north-south.\nfind a planisphire.it's a star chart which is very easy 2 use.

Due North.  There are a couple of ways to find it.  One is to face due north and look up a bit.  If you know your latitude, you can find the North Star by looking up that many degrees from the horizon.  Hence, if you're in SF like me, the North Star will be ~38 degrees above the horizon.\n\nThe easier way is to find the Big Dipper\nhttp://www.wsanford.com/~wsanford/exo/constellations/bigdipper.gif\nWhich is a prominent and easy constellation to find in the northern sky.  Then, close one eye, stretch out your arm, and spread your fingers so that the front two stars (across from the "handle") are each covered by one of your fingers.  Those front two stars point right at the North Star.  Trac out in a straight line from those two stars, going "up" (if you imagine the dipper being oriented in a way that it would hold water) for a distance that is five times the distance between those two front stars.  So if you swing your arm along, placing the lower finger where the top finger just was, and keeping the spacing of your fingers steady, it will direct you to a bright star.  That star is the North Star.

north star is actually a pole star which is situates on the axis of the pole and it is the only star which does not moves and remains fixed in its position. in ancient times the people use to locate the direction by seeing the pole star as it is located in north. it was used by sailors tooo
