A magnet was brought from different directions towards a toy boat that has been floating in water in a tub. Affect observed in each case is stated in Column I. Possible reasons for the observed affects are mentioned in Column II. Match the statements given in Column I with those in Column II.
| Column I | Column II |
| Boat gets attracted towards the magnet | Boat is fitted with a magnet with north pole towards its head |
| Boat is not affected by the magnet | Boat is fitted with a magnet with South pole towards its head. |
| Boat moves towards the magnet if North pole of the magnet is brought near its head. | Boat has a small magnet fixed along its length. |
| Boat moves away from the magnet when North pole is brought near its head. | Boat is made of magnetic material. |
| Boat floats without changing its direction. | Boat is made up of non-magnetic material |

Explain why the bulb would not glow in the arrangement shown in Fig. 9.13.

Complete the drawing shown in Fig. 9.14 to indicate where the free ends of the two wires should be joined to make the bulb glow

Would the bulb glow after completing the circuit shown in Fig. 9.14 if instead of safety pin we use an eraser?
