magnets attract
To find the north pole of a magnet you can use a pole identifier. When the identifier is held to the magnet, you press a button and it will tell you if it is the north or south pole.
Well there isn't any positive or negative on a magnet. But to find North and South, you can suspend a bar magnet on a string and see which way it points, or use a compass. Remember that the North Magnetic Pole defines what Magnetic North is, and on a compass or a bar magnet the SOUTH magnetic pole point at it.
Use a compass. It will point to a magnet's south pole.
suspend the magnet from a string at its center of gravity. The north pole of the magnet will point to the north pole. (The north magnetic pole of the earth is actually a south seeking pole.)Another AnswerUse a compass. It's north seeking pole will be attracted towards the magnet's south pole and its south-seeking pole will be attracted towards the magnet's north pole.
Use a compass. It's needle points to the south pole of a magnet.

A compass.
A spectroscope, possibly. A magnet is not the correct answer because there are several metallic elements which are magnetic.

You can use 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 AnswerUse a compass. It's needle will point to the magnet's south pole.
You could use magnets to push things like another magnet or you could pull metal things to it.
