You are given an iron strip. How will you turn it into a magnet?
Making a magnet : Take an iron strip and place it on the table. Now take a bar magnet and place one of its poles near one edge of the strip of iron. Without lifting it move it along the length of the iron strip till you reach the other end. Now lift the magnet and bring the pole to the same point of strip and observe that the strip attracts the fillings. This indicates that the iron strip becomes magnet. Remember that the pole of magnet and direction of its movement should not change.
