Solution
Single touch method is one of various ways of making a magnetic material like soft iron into a magnet.
In this method one end of the magnet (say north pole) is placed at one end (say end A) of the iron piece and then rubbed over the bar from end to other (say end B), then lifted and brought back to first end. This process is repeated for few times. You will observe that the original end that is end A will become North pole and end B becomes South pole.
