Access Answers to Lakhmir Singh Solutions for Class 10 Physics Chapter 2 Magnetic Effects of Electric Current
Q1. Mention any two characteristics of magnetic field lines.
Answer:
a) Magnetic field lines begin from the north pole and end at the south pole.
b) Magnetic field lines never cross each other.
Q2. How can you observe the magnetic field pattern of a bar magnet?
Answer:
a) By sprinkling iron filings around the magnet.
b) By using a magnetic compass to trace the direction of the field.
Q3. How can you tell where the magnetic field is strongest by looking at its pattern?
Answer:
The magnetic field is strongest where the field lines are closest together.
Q4. Is this statement true or false: The Earth’s magnetic axis and geographical axis are the same?
Answer:
False. The magnetic axis and the geographical axis of the Earth are tilted at an angle of about 15 degrees.
Q5. Why does a compass needle change direction near a bar magnet?
Answer:
Because the bar magnet creates a magnetic field that affects the needle of the compass.
Q6. Where is a magnetic strip used in a refrigerator and why?
Answer:
A magnetic strip is placed in the door of the refrigerator to help keep it tightly closed.

Q7. Fill in the blanks:
a) Magnetic field lines leave the ____ pole of a bar magnet and enter at its ____.
b) The Earth’s magnetic field is like that of a ____ magnet with its ____ pole in the northern hemisphere.
Answer:
a) north, south
b) bar, south
Q8. What is a magnetic field and how can we find its direction?
Answer:
A magnetic field is the space around a magnet where magnetic force is felt. Its direction can be found using a compass; the compass needle aligns with the field, and the north end points in the direction of the magnetic field.
Q9. Why don't two magnetic field lines cross each other?
Answer:
Because if they did, it would mean the magnetic force at that point is in two directions, which is not possible.
Q10. Why doesn't an electric iron wire attract metal objects even when current flows through it?
Answer:
Because the magnetic field created by the current in the wire is too weak to attract metal objects.
Q11. a) What are magnetic field lines? Describe an activity to draw a magnetic field line from one pole of a bar magnet to the other.
b) Why does a magnet always point in the north-south direction when freely suspended?
Answer:
a) Magnetic field lines show the direction and strength of a magnetic field.
Activity: Place a bar magnet on a piece of paper and fix it. Put a compass near the north pole and mark where the needle points. Move the compass along that direction, marking each point. Join all the points to make a smooth curve from the north to the south pole.
b) A freely suspended magnet points north-south because Earth itself acts like a big magnet, with its magnetic south pole near the geographic north.
Q12. A strong bar magnet is placed vertically above a wooden board. The magnetic lines of force will be:
Answer: d) in all the planes around the magnet
Q13. The magnetic field lines of a bar magnet:
Answer: c) originate from the north pole and end at its south pole
Q14. Which material is not attracted by a magnet?
Answer: c) brass
Q15. Magnetic field lines:
Answer: c) do not cross one another
Q16. The north pole of Earth’s magnet lies in the:
Answer: a) geographical south
Q17. The angle between Earth’s magnetic axis and geographical axis is about:
Answer: b) 15°
Q18. The shape of Earth’s magnetic field is similar to that of:
Answer: d) bar magnet
Q19. A magnet attracts:
Answer: d) iron and steel
