Answer:
You can convert an iron strip in to a bar magnet using single touch method. Take a bar magnet and place its pole near one edge of the iron bar. Without lifting the bar magnet, move it along the length of iron bar. When the magnet reaches the other end lift it up and again move the magnet along the iron bar. Repeat it 30-40 times. Check whether it has become a magnet. If not continue the process for some more time.
