  I. Select the Correct Option Which of these is not a magnetic material? (c) Zinc . (Iron and Cobalt are magnetic ). Which of these is used to make a permanent magnet? (a) Steel . (Soft iron is typically used for temporary magnets ). If the north poles of two magnets are placed near one another, there: (b) is a repulsion between them . (Like poles repel ). Observe the pictures A and B (toy cars with magnets): (c) In A, cars 1 and 2 will move away and in B, 3 and 4 will come closer to each other . Reasoning : In A, like poles ($S$ and $S$) face each other, causing repulsion. In B, unlike poles ($S$ and $N$) face each other, causing attraction. The correct arrangement to store two magnets is: (b) . Reasoning : Bar magnets should be stored in pairs with unlike poles on the same side, separated by wood, and with soft iron keepers across the ends. The st...
