When an unmagnetised bar of a magnetic material such as soft iron or steel , is placed near or in contact with a magnet , the bar becomes a magnet ie it acquires the property of attracting
iron filings when they are brought near it's ends. if the magnet is now removed, it is seen that nearly all the iron filingswhich have clung to it fall down ie the bar looses it's magnetism
