In this page we have NCERT Solutions for Class 6 Science Chapter 13 Fun with Magnets. Hope you like them and do not forget to like , social share and comment at the end of the page.
Question 1
Fill in the blanks in the following:
(i) Artificial magnets are made in different shapes such as ___ , ___ and _____ .
(ii) The Materials which are attracted towards a magnet are called___.
(iii) Paper is not a ___ material.
(iv) In olden days, sailors used to find direction by suspending a piece of ____.
(v) A magnet always has ___ poles (i.e. North Pole and South Pole).
Answer
(i) bar-magnet, cylindrical, horse-shoe magnet
(ii) magnetic materials
(iii) Magnetic
(iv) bar magnet
(v) two
Question 2
State whether the following statements are true or false.
(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. It has two poles
(ii)) False. Natural magnets are discovered in Greece
(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
Pencil sharpener has the plastic body but The blade of the pencil sharpener is made of iron. Iron is a magnetic in nature. That is the reason 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.
Column I
Column II

Question 5
Write any two properties of a magnet.
Answer
Some of the properties are
  1. Each magnet has two poles i.e. North Pole(N) and South Pole(P)
  2. Opposite poles of two magnet attract each other while like poles of two magnet repel each other.
    N-N
    Repulsion
    N-S
    Attraction
    S-N
    Attraction
    N-S
    Repulsion
  3. A freely suspended magnet always aligns in N-S direction.
Question 6
Where are poles of a bar magnet located?
Answer
The two ends of the bar magnet represent the two poles.
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
Hang up the magnet by a cotton thread so that it hangs freely. When it comes to rest, we notice that the magnet is lying in a North - South direction
Magnetic compass works on the same principle. In past it was used by sailors or travelers to find directions.

Question 8
You are given an iron strip. How will you make it into a magnet?
Answer
This can be achieved using touch and stroke method. We will need a bar magnet to achieve this
Step 1: Take a rectangular piece of iron. Place it on the table.
Step 2: Take a bar magnet and place one of its poles near one edge of the bar of iron.
Step 3: Without lifting the bar magnet, move it along the length of the iron bar till you reach the other end.
Step 4: Lift the magnet and bring the pole (the same pole you started with) to the same point of the iron bar from which you began Step 5: Move the magnet again along the iron bar in the same direction as you did before.
Step 6: Repeat this process about 30-40 times.
Very soon iron strip will become magnet
You can check it by bringing few pins near to the iron piece
Question 9
How is a compass used to find directions?
Answer
A compass has a magnetic needle attached to it which can rotates freely. A freely suspended magnet always aligns in N-S direction. The red coloured magnetic needle points to North direction. Once we know North direction, we can easily find out the other directions.
E.g. 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 inColumn 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 non-magnetic material
Answer:
Column I
Column II
Boat gets attracted towards the magnet Boat is made of magnetic material
Boat is not affected by the magnet
Boat is made up non-magnetic material
Boat moves towards the magnet if north
pole of the magnet is brought near its
head
Boat is fitted with 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 with a magnet with north
pole towards its head
Boat floats without changing its direction. Boat has a small magnet fixed along its
length
