CBSE Class 6 Science Exploring Magnets (Class 6 NCERT New) Quiz 8

1. What does the needle of a magnetic compass indicate?

A North-south direction B East-west direction C Up-down direction D Left-right direction

2. How is the magnet in a compass typically mounted?

A On a pin so it can rotate freely B Glued to the bottom of the box C Hanging from a string D Fixed and unable to move

3. Which of the following materials is NOT required to make a simple magnetic compass as described in the activity?

A Cork piece B Iron sewing needle C Permanent bar magnet D Plastic spoon

4. What do you observe when you bring the same poles (either North-North or South-South) of two bar magnets close to each other?

A They repel each other. B They attract each other. C They stick together. D They lose their magnetic properties.

5. Why is it important to make sure that the two magnets do not touch each other during the experiment described in the activity?

A To observe the force of attraction or repulsion without interference. B To prevent the magnets from breaking. C To keep the pencils in place. D To make the magnets stronger.

6. Suppose you perform the experiment and notice that magnet A always moves towards the approaching magnet B, regardless of which end is brought near. What can you infer about the poles of the magnets?

A The ends being brought together are unlike poles. B The ends being brought together are like poles. C The magnets are not working. D The pencils are affecting the experiment.

7. Which instrument is used in the activity to observe the effect of a bar magnet?

A Magnetic compass B Thermometer C Barometer D Voltmeter

8. What should you do first when using a magnetic compass in the experiment?

A Place it over a horizontal surface and wait for the needle to come to rest B Shake it vigorously C Place it near a heater D Cover it with a cloth

9. When the North pole of a magnet is brought closer to the North pole of the compass needle, what happens to the compass needle?

A It moves away B It moves closer C It spins rapidly D It does not move

10. What is the purpose of placing a piece of wood between the magnet and the compass needle in the experiment?

A To test if the wood affects the magnetic field and the compass needle's deflection B To make the compass needle spin faster C To protect the magnet from damage D To measure the weight of the wood
