becouse at north &south poles the pole strength is more than other part of bar magnet so attraction is also more at poles Theoretically, magnet's lines of force - as evinced by the iron filings - encompases all universe, but, nonetheless, they meet together at the magnet's poles

What do magnetic field lines that curve away from each other show?
The difficulty of attempting to measure something, without altering it by the attempt, is well shown in attempting to measure magnetic field lines.First, the lines of magnetic force are an artificial construct - in the same way as many contour lines are.Consider the 'field lines' between two poles of a magnetic. The magnetic field concerned will vary in a perfectly smooth manner as one moves away from the most central position between the two poles, to the positions most remote from the poles. There is no reason to believe that any one curve between the poles is preferred over any other; or any more real.When we sprinkle iron filings on the region between the two poles, we alter the properties of the field in a most egregious manner.The iron filings are ferromagnetic, and an individual filing thus concentrates the field in its region. AND the individual filing will have its own North and South pole.These filings will form a chain of interconnected filings, each with its own N and S poles, and attracted to the N and S poles of the next filing in that line.At the same time, the N and S poles of an individual filing will REPEL from adjacent similar fields. Thus there will appear to be lines of filings, roughly parallel to each other, and becoming closer as they approach the high intensity of the magnet's real poles.A similar problem will occur when attempting to measure the strength of an electrostatic field. For any dust sensitive to an electrostatic field will attract surplus electrons to itself, thus distorting the image of the field.
How can you determine the poles of an odd shaped magnet?
You place the magnet under a piece of paper, and then sprinkle some iron filings on the paper. The iron filings will line up along the magnetic lines of force, which will show very clearly where the magnetic poles are.
Where is a magnets pull the strongest?
The north and south poles.
How do the iron filings behave when sprinkled over the bar or horseshoe magnet?
spread out from one pole and curve around to the other
What poles attract and what poles repel?
poles of the same kind repel one another. poles of differet kinds attract, and this is where the saying ' opposites attract' comes from.
What is pole strength?
unlike poles aatract Pole strength is the ability of the two fictitious north and south poles to attract the iron filings. The pole strength of north pole is assumed to be '+m' and that of south pole is '-m'. Its SI unit is Ampere-metre.

What is a pole on a magnet?
The poles of a magnet are the ends of the core of the magnet, where the lines of force emerge. An experiment with iron filings shows the lines of force, by putting a sheet of paper over the magnet and sprinkling fine iron filings. This is an easy thing to do at home. For a bar magnet the poles will be at opposite ends. If you have two such magnets you can experiment and find that like poles repel, opposite poles attract.
What is contained in iron filings?
Iron filings come from Iron that has been through some sort of machinery that has been used to shape it and the filings are the leftovers.
What is the two unlike poles on a magnet?
North and south poles.
Where is a magnets pull the strongest?
The north and south poles.
Are the North Pole and the south pole geographical poles?
yes, the north and south poles are geographical poles.
Lines of longitude meet where?
Lines of longitude meet at the North and South Poles.
How do the iron filings behave when sprinkled over the bar or horseshoe magnet?
spread out from one pole and curve around to the other
What do we call ends of magnet?
North and South (Poles) :)
