उत्तर
The magnetization of Iron Bar by Single Touch Method: Place the iron piece on the table and stroke it with a bar magnet from A to B with one end of the magnet. When the magnet reaches B it is lifted and brought back to A to repeat the stroke. After a few strokes, we will notice that A has acquired the same polarity as the pole rubbed against it.
