Case Study Based Questions

Case Study: Rahul visited a science laboratory where he observed different types of magnets. His teacher suspended a bar magnet freely using a thread. After a few seconds, the magnet came to rest in the north-south direction. The teacher then brought another magnet close to it. Rahul noticed that sometimes the magnets attracted each other, while at other times they repelled each other.

1. Why did the freely suspended magnet come to rest in the north-south direction?
2. What does this activity tell us about the Earth?
3. Under what condition did the magnets repel each other?
4. Which property of magnets is demonstrated in this activity?
5. Why is repulsion considered the surest test of a magnet?

Competency Based Questions

1. Collect five objects from your classroom and classify them as magnetic or non-magnetic with proper reasons.
2. Prepare a simple magnetic compass using household materials and explain how it works.
3. Observe the use of magnets in your home and prepare a list of at least eight applications.
4. Design a simple experiment to show that magnetic force can pass through non-magnetic materials.
5. Prepare a comparison chart showing the differences between natural magnets and artificial magnets.

HOTS Questions (Higher Order Thinking Skills)

1. If magnets had only one pole instead of two, how would their behaviour change? Explain your answer.
2. Why do you think modern electronic devices should be kept away from strong magnets?
3. Imagine the Earth suddenly lost its magnetic field. What difficulties would travellers, birds, and animals face?
4. How would life be different if magnets did not exist? Explain with suitable examples.
5. Suggest five innovative ways in which magnets can be used to solve real-life problems in the future.
