(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 the olden days, sailors used to find direction by suspending a piece of ______.
(v) A magnet always has ______ poles.
Ans:
(i) Artificial magnets are made in different shapes such as bar-magnet, cylindrical magnets and horseshoe magnets.

Cylindrical magnet(ii) The Materials which are attracted towards a magnet are called magnetic materials.
(iii) Paper is not a magnetic material.
(iv) In the olden days, sailors used to find direction by suspending a piece of bar magnet.

(v) A magnet always has two poles.
Magnet having two poles (North & South)Q2. State whether the following statements are true or false.

• It contains a blade made of iron.
• Iron is a magnetic material, which is why it responds to the magnet.

Q4. 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.

Ans: 

 
Q5. Write any two properties of a magnet.
Ans: Two properties of a magnet are as follows:
(i) Like magnetic poles repel each other and unlike magnetic poles attract each other.
(ii) A freely suspended magnet always aligns in N-S direction.

Q6. Where are poles of a bar magnet located?
Ans: The poles of bar magnet are located at its two end points.
Two Poles

Q7. A bar magnet has no markings to indicate its poles. How would you find out near which end is its north pole located?
Ans:  To find the north pole of a bar magnet without markings, you can follow these steps:

• Suspending the magnet freely allows it to rotate.
• Once at rest, the magnet will align itself in the north-south direction.
• The end pointing towards the north is the north pole.
• The opposite end, pointing towards the south, is the south pole.

Q8. You are given an iron strip. How will you make it into a magnet?
Ans:  An iron strip can be turned into a magnet by following these steps:

• Place the iron strip on a flat surface.
• Take a bar magnet and hold one of its poles near one end of the iron strip.
• Without lifting the magnet, move it along the length of the iron strip to the other end.
• Lift the magnet and return it to the starting point.
• Repeat the movement in the same direction.

Continue this process for at least 30-40 times. After this, the iron strip will become a bar magnet with two poles. To check if it has magnetised, bring a pin or some iron filings close to the strip. If it does not attract them, repeat the process until it does.

Q9. How is a compass used to find directions?
Ans: A compass consists of a magnetic needle that can move freely.

• The needle aligns itself in the north-south direction when the compass is still.
• The end of the needle painted in red indicates the north pole.
• The opposite end points to the south pole.

This simple tool has been used for centuries to help travellers find their way.

Q10. A magnet was brought from different directions towards a toy boat that has been floating on water in a tub. The effect observed in each case is stated in Column I. Possible reasons for the observed effects are mentioned in Column II. Match the statements given in Column I with those in Column II.

Ans:
