G You are given three iron rods. Two of them are magnets but the third one is not. How could you use the two magnets to find that the third rod is not magnetized? The two magnets will be attracted to one another. The iron bar that is not attracted to either of the other magnets is, therefore, not magnetized. It is impossible to determine which of the iron rods are not magnetized. Use both ends of one iron rod to approach the other iron rods. If both ends of the rod you are holding repel both ends of the other two rods, then the one you are holding is not magnetized iron. Use both ends of one iron rod to approach the other iron rods. If both ends of the rod you are holding attracts both ends of the other two rods, then the one you are holding is not magnetized iron.
