(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.

(vii) Rubber is a magnetic material.
(i) False
(ii) True
(iii) True
(iv) False
(v) True
(vi) False
(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.
A pencil sharpener contains some iron parts.

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 N-N ……………… N-….. Attraction S-N ………………. …..-S Repulsion

 Position of two magnets Behavior N-N Repulsion N-S Attraction S-N Attraction S-S Repulsion

Question 5.
Write any two properties of a magnet.

• Magnet attracts magnetic substances.
• Magnet when freely suspended always points in north-south directions.

Question 6.
Where are poles of a bar magnet located?
Poles of a bar magnet are located at the ends.
When a bar magnet is placed near some iron filings, we observe more iron filings clinging to the magnet near its ends.
See Figs. 13.3 and 13.4(a).

The ends of a magnet where maximum iron filings get clung, i.e., the attraction is strongest, are known as 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?
When a bar magnet is suspended freely, it always rests in north-south directions. The end pointing towards north is called north seeking end or the north-pole and the end pointing towards south is called south seeking end or the south-pole of the magnet. Usually, north (N) and south (S) poles are marked on the magnets (Fig. 13.4).

Question 8.
You are given an iron strip. How will you make it into a magnet?
We can convert an iron strip by repeatedly stroking it by a bar magnet systematically. Take the iron strip and keep it on a wooden table. Stroke it with one pole of a bar magnet in one direction. When you reach the other end of the iron strip, lift the magnet and bring the same pole back to the starting end of the iron piece, stroke again, in the same direction. Repeat this process about 30-40 times. After that check the iron strip whether the iron strip has now become a magnet. If not, continue the process for some more time. Remember the pole of the magnet and the direction of stroking is not to be changed. In the same way, iron needle can also be converted into a magnet.

Question 9.
How is a compass used to find directions?
Magnetic compass is a small magnetic needle enclosed in a glass case. The magnetic needle is fixed at the centre so that it can move freely. When kept on a table top, the needle of the compass will come to rest pointing in the north-south directions. It is thus used in the laboratory to mark directions. See Fig. (13.5).

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,

 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
