Final Answer:
Q1. non-contact
Q2. newton (N)
Q3. repel, attract
Q4. iron, nickel, cobalt
Q5. bar magnet
Q6. magnetic field lines
Q7. Left end: N, Right end: S
Q8. a) false, b) true, c) true, d) false, e) false
Q9. At the poles (ends); because the field lines are closest together there.
Q10. A magnet that keeps its magnetic properties without needing an external field (e.g., a fridge magnet).
Q11. A temporary magnet created when a magnetic material is placed in a magnetic field (e.g., an iron nail near a magnet).
Q12. attraction
Q13. The iron filings line up along the magnetic field lines, showing the shape of the field.
Q14. Bar ③ (E–F), because it repels — only a magnet can repel another magnet; unmagnetized iron would be attracted.
Q15. a) Field lines go outward from both ends and do not connect (they push apart).
b) Same as (a), but arrows point inward on both ends.
c) Field lines go from N (left) to S (right), connecting the two magnets.
Q16. a) Both are non-contact forces that act at a distance; gravity always attracts, magnetism can attract or repel.
b) Both involve fields and act without contact; electrostatic forces act between charges, magnetism between poles/moving charges.
