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.

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.
