Final Answer:
Q2. Newton (N)
Q3. repel, attract
Q4. Iron, nickel, cobalt
Q5. Bar magnet
Q6. Magnetic field lines
Q7. Left end: N, Right end: S
Q8a. False
Q8b. True
Q8c. False
Q8d. False
Q8e. False
Q9. At the poles (ends); because field lines are closest together there
Q10. A magnet that keeps its magnetic properties without needing an external field
Q11. A magnet created only when placed in a magnetic field (temporary)
Q12. attraction or repulsion
Q13. Iron filings align along the magnetic field lines, showing their shape
Q14. Bar ② — it is not attracted, so it’s unmagnetized iron (magnetized bars would attract or repel)
Q15a. Field lines curve away from both ends (no connection between them)
Q15b. Field lines curve toward both ends (no connection between them)
Q15c. Field lines go from N (bar 1) to S (bar 2), connecting the two
Q16a. Similarity: both are non-contact forces; Difference: gravity always attracts, magnetism can attract or repel
Q16b. Similarity: both act at a distance and follow inverse-square laws (approximately); Difference: electrostatic forces act on charges, magnetism on moving charges/magnetic materials
