On the top.\n\nOh..... hold on a minute!

Iron, cobalt and nickel can be magnetic. They can be made to have polarity. Poles that are alike repel and poles which are not alike attract. A magnet will attract all of them if they are not polarized. If they are polarized, a magnet will attract or repel according to the polarity.\n;-D

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!

It will align with whatever magnetic field it is closest to or align itself on a piece of metal. If it isn't close to either of these, it will point in any random direction.

You mean 2 P of a M which is 2 poles of a magnet.

It all depends in what sense. With magnets you have a north and a south pole, same as the earth. different poles attract, same propel away. In terms of electricity you have negitive and postive thouch both of them together and you get a spark.

If you are at the North pole, it would settle on one of the other north poles.  Actually, there are three of them.  Closely spaced but technically three.   \n\nIf you were at the magnetic center point, the needle would probably dip down a little and lose all directional reference. Probably would not "spin", but would be subject to randon movement.

See the listing of suppliers given in the source below.  If you want to do magnetic separation, you'll want multi-domain particles, which means using particles *larger* than about 100 nm (depending on the material).

A dipole (Greek: di(s) = double and polos = pivot) is a pair of electric charges or magnetic poles of equal magnitude but opposite polarity (opposite electronic charges), separated by some, usually small, distance. Dipoles can be characterized by their dipole moment, a vector quantity with a magnitude equal to the product of the charge or magnetic strength of one of the poles and the distance separating the two poles. The direction of the dipole moment corresponds, for electric dipoles, to the direction from the negative to the positive charge. For magnetic dipoles, the dipole moment points from the magnetic south to the magnetic north pole — confusingly, the "north" and "south" convention for magnetic dipoles is the opposite of that used to describe the Earth's geographic and magnetic poles, so that the Earth's geomagnetic north pole is the south pole of its dipole moment. Because of the absence of magnetic monopoles, magnetic dipoles are actually created by current loops or by quantum-mechanical spin.

use a collimator.or magnetic fields.

Sorry, but as far as I can tell, it doesn't exist.\n\nThen again, I know nothing about this area of interest.\nI like enio_giacomini's answer. Go with that.\nThen again, he answered that "magnet" question with "In center," which makes no sense at all.  Whatever. Your call.

Its not so much one pole attracting the needlepoint so much as the entire magnetic metal beneath the needle aligning to the magnetic field lines*. North and South are just directional names; the most powerful magnet at the time magnetism was discovered was the earth, so naturally, they used the locations of the Earth's poles to name every magnet's pole.\n\n*Magnetic field lines are lines of force connecting the North and South poles of every magnetic object. Place a magnet under a piece of paper and sprinkle iron filings on top, and you'll be able to 'see' them. \n\nThe magnetosphere is the name given to the Earth's magnetic field, which extends into space and gives us protection against much of the charged particle radiation from the sun. This 'solar wind' interacting with our magnetosphere is what causes the auroras over the poles.

A compass would be useless at the magnetic poles.  That's because compass needs not only point north, but they also align themselves with Earth's magnetic field.  In the low latitudes, a compass needle will be more or less parallel to the surface.  Near the magnetic pole, though, the compass needle will try to point "into" the ground, following the lines of force; being incapable of that, it will no longer be useful.

There are actually four north poles. Neither of them have a sign as the some of the poles tend to woble. They are as follows:\nThe North Magnetic Pole – the point on the Earth's surface where the Earth's magnetic field points directly downwards. This pole is constantly wandering; its estimated 2005 position was 82.7° N 114.4° W. \nThe North Geomagnetic Pole – the point of intersection of the Earth's surface with the axis of a simple magnetic dipole (like a bar magnet) that best approximates the Earth's actual more complex magnetic field. Like the North Magnetic Pole it constantly wanders; as of 2005 it was located at approximately 79.74° N 71.78° W. \nThe Northern Pole of Inaccessibility – the point in the Arctic Ocean farthest from land, at 84°03′N 174°51′W. \nThe North Celestial Pole – an imaginary point in the northern sky towards which the Earth's axis of rotation points.
