NCERT Solutions for Class 6 Science Chapter 13 Fun with Magnets
1.Fill in the blanks in the following:
(i) Artificial magnets are made in different shapes such as __________, __________ and ____________.
Answer: bar magnet, horse shoe magnet and a ball – ended magnet
(ii) The Materials which are attracted towards a magnet are called________.
Answer: magnetic materials
(iii) Paper is not a ______ material.
Answer: magnetic
(iv) In olden days, sailors used to find direction by suspending a piece of ___________.
Answer: natural magnet
(v) A magnet always has __________ poles.
Answer: two ( north and south )
2. State whether the following statements are true or false:
(i) A cylindrical magnet has only one pole.
Answer: False. [ Every magnet has two poles. A cylindrical magnet also has two poles. ]
(ii) Artificial magnets were discovered in Greece.
Answer: False. [ Natural magnets were discovered in greece. ]
(iii) Similar poles of a magnet repel each other.
Answer: True.
(iv) Maximum iron filings stick in the middle of a bar magnet when it is brought near them.
Answer: False. [ Maximum iron filings stick to both end i.e both poles of a bar magnet, when it is brought near them. ]
(v) Bar magnets always point towards North-South direction.
Answer: True.
(vi) A compass can be used to find East-West direction at any place.
Answer: True.
(vii) Rubber is a magnetic material.
Answer: False. [ Rubber is a non-magnetic material. ]
3. It was observed that a pencil sharpener gets attracted by both the poles of a magnet although its body is made of plastic. Name a material that might have been used to make some part of it.
Answer: The body of a sharpener is made of plastic but the blade in the sharpener is made of iron. Iron is a magnetic material and gets attracted towards the magnet. Hence, the pencil sharpener gets attracted by both the poles of a magnet.
4. Column I shows different positions in which one pole of a magnet is placed near that of the other. Column II indicates the resulting action between them for each situation. Fill in the blanks.
| Column I | Column II |
|---|---|
| N – N | ______ |
| N – ______ | Attraction |
| S – N | ______ |
| ______ – S | Repulsion |
Answer:
| Column I | Column II |
|---|---|
| N – N | Repulsion |
| N – S | Attraction |
| S – N | Attraction |
| S – S | Repulsion |
5. Write any two properties of a magnet.
Answer: Properties of magnet –
- Magnets attract magnetic material.
- Like poles of magnet repel each other and unlike poles attract each other.
6. Where are poles of a bar magnet located ?
Answer: North Pole is located on one end and South Pole is located on the other end of the bar magnet.
7. A bar magnet has no markings to indicate its poles. How would you find out near which end is its north pole located?
Answer: Take a bar magnet and suspend it freely using a thread. The north pole and south pole always come to rest towards north and south direction respectively. Thus, one can find poles of bar magnet by suspending it freely using thread.
8. You are given an iron strip. How will you make it into a magnet ?
Answer: Place an iron strip on table. Bring one end of bar magnet near the iron strip and move it from this end towards the other end. After reaching the other end, move the magnet back towards the end we started. Repeat this process 40 to 50 times. Now, check if iron strip is converted into magnet, by bringing some iron fillings near it. If iron filling stick to iron strip, then iron strip is converted into magnet. If not, then repeat same process for some more time.
9. How is a compass used to find directions ?
Answer: A compass always points towards the North South direction. Red coloured needle of the compass always points the North direction. If you are facing the North, then backward direction will be south, left of north will be west and right of the north will be east.
10. 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 |
|---|---|
| Boats get attracted towards the magnet | Boat is fitted a magnet with north pole towards its head |
| Boat is not affected by the magnet | Boat is fitted 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 fits 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 non-magnetics material |
Answer:
| Column I | Column II |
|---|---|
| Boats get attracted towards the magnet | Boat is made of magnetic material |
| Boat is not affected by the magnet | Boat is made up non-magnetics material |
| Boat moves towards the magnet if north pole of the magnet is brought near its head | Boat is fitted a magnet with south pole towards its head |
| Boat moves away from the magnet when north pole is brought near its head | Boat is fitted a magnet with north pole towards its head |
| Boat floats without changing its direction | Boat has a small magnet fits along its length |
