उत्तर
Take the magnet that has the North and South poles marked on it. Keep both iron bars next to it and both will be drawn to it since they are magnetic. So, one after the other, test each of the two magnet bars for repulsion. If the first magnet bar you grabbed repels the specified magnet bar, this will be the second one. Magnets both attract and repel, whereas iron attracts.
