Question 1. 
Boojho has this question for you. A tailor was stitching buttons on his shirt. The needle has slipped from his hand onto the floor. Can you help the tailor to find the needle?
Answer:
Needle is made up of iron. Iron is attracted towards magnet. Therefore, to find the needle that falls on the ground, tailor can use a magnet or “Magnet stick”.

Question 2. 
Paheli has this puzzle for you. You are given two identical bars which look as if they might be made of iron. One of them is a magnet, while the other is a simple iron bar. How will you find out, which one is a magnet? 
Answer:
As we know that similar poles of magnet repel and unlike poles of magnet attract each other. So, to know which one is magnet, bring another magnet close to them and test the repulsion property. The bar which shows repulsion is a magnet. Repulsion is a sure test for magnet.

Question 3. 
Boojho has this question for you. What will happen if a magnet is brought near a compass?
Answer:
If a magnet is brought near a compass, it will act in the same manner as we bring two magnets closer to each other.

(i) A cylindrical magnet has only one pole.
(ii) Artificial magnets were discovered in Greece.
(iii) Similar poles of a magnet repel each other.
(iv) Maximum iron filings stick in the middle of a bar magnet when it is brought near them.
(v) Bar magnets always point towards North - South direction.
(vi) A compass can be used to find East - West direction at any place.
(vii) Rubber is a magnetic material.
Answer:
(i) False 
(ii) True 
(iii) True
(iv) False 
(v) True
(vi) True 
(vii) False. 

Question 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 blade of the pencil sharpener is made of iron and iron gets attracted to both the poles of a magnet. Therefore, sharpener gets attracted by the poles of a magnet.

Question 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:

Answer:

Question 5. 
Write any two properties of a magnet.
Answer:
The two properties of magnet are:

1. Each magnet has two poles, i.e. North Pole (N) and South Pole (S). Opposite poles of two magnets attract each other and like poles of two magnets repel each other.
2. A freely suspended magnet always rests in North - South (N - S) direction.

Question 6. 
Where are poles of a bar magnet located?
Answer:
Poles of a bar magnet are located at the two ends of the bar magnet.

Question 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:
Suspend a magnet freely with the help of a thread and wait till it comes to rest. The end of the magnet that points to the north direction will be regarded as the North Pole of the magnet. The other end is regarded as the South Pole.

Question 8. 
You are given an iron strip. How will you make it into a magnet?
Answer:

1. To make our own magnet we take a rectangular piece of iron. We place this iron piece on the table and take a bar magnet and move the bar magnet along the length of the iron bar till we reach the other end without lifting it.

2. Now, lift the magnet and go to the starting end from where you started and move the magnet again along the iron bar in the same direction as you did before. Repeat this again and again for 30 - 40 times. Our magnet is ready.

Question 9. 
How is a compass used to find directions?
Answer:
Compass needle acts as a hanging magnet. So, when we place the compass, its needle rests in North - South direction. The red coloured magnetic needle points to North direction. Once we know North direction, we can easily find out the other 
directions. For example - if North is upwards, South is downward side, East will be on right hand side and West shall be on left hand side.

Question 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.
