The North end of a freely suspended magnetic needle gets attracted towards a piece of soft iron placed a little distance away from the needle. Why?

The property of attraction is in magnets can attract any iron, steel or metal (some or most of them), and so the iron piece got attracted to the magnet.

awesomeraghav: first, iron is also a metal

awesomeraghav: so it need not be written sepertely

awesomeraghav: seperately

Anonymous: Yeah I meant that.....

awesomeraghav: also, iron alongwith nickel and cobalt is the only metal that attracts magnet

awesomeraghav: and steel sometimes

Anonymous: Ok

awesomeraghav: : )

Not only the north end, the south end could also be attracted.
Reason--
The magnetic needle is freely suspended, hence can rotate in any direction.
It gets attracted to the soft iron piece, because it is in its magnetic field. Because the iron can not move much (the needle is most probably light enough to be freely suspended, and hence is not large enough to provide a magnetic force large enough to move the magnet), the needle moves instead, towards the soft iron piece, and stays there until either the iron moves out of the needle's magnetic field or the needle moves away.
