Que. 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.

Ans. 3 Metals like Iron, Cobalt and Nickel could have been used to make some parts of the sharpener.

Que. 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

Ans. 4 The filled table is:

Que. 5 Write any two properties of a magnet.

Ans. 5 Some of the important properties of a magnet are:

• A magnet attracts the materials made up of iron, cobalt and nickel.
• Each magnet has two poles irrespective of their size and shape.
• Like poles of magnets repel each other and unlike poles of magnets attract each other.

Que. 6 Where are the poles of a bar magnet located?

Ans. 6 The poles of a bar magnet are located on the two ends of it.

Que. 7 A bar magnet has no markings to indicate its poles. How would you find out near which
end is its north pole located?

Ans. 7 We can find out about the north pole an unmarked bar magnet by hanging in freely in air with a thread and the end of the bar magnet that will point toward the North direction will be the north pole of our bar magnet.

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

Ans. 8 We can convert an iron strip into an artificial magnet by using a bar magnet and by following this procedure:

• Place the iron strip on a wooden table.
• Now take a bar magnet and place its one pole either the North or South pole on one end of the iron strip.
• Without lifting the bar magnet, move it along the length of the iron strip till you reach the other end.
• Now, lift the magnet again, bring the same pole to the starting point and repeat the rubbing.
• Do it at least 30-40 times and check if the piece of iron is magnetised or not by trying to lift up some iron staples with it.
• If you are able to lift up the iron staples with your iron strip, then your iron strip has become an artificial magnet.

Que. 9 How is a compass used to find directions?

Ans. 9 A compass is generally a small box with a glass cover and a magnetised needle is pivoted inside that box. A compass also has a dial with directions marked on it.

Here is a procedure for using a compass for finding directions:

• The compass is kept at a place where we wish to know the directions.
• Its needle indicates the North-South direction when it comes to rest.
• Then the compass is rotated in such a way that the North-South marked on the needle aligns with the North and South marked on the dial of the compass.
• Now, compass’s magnetic needle is pointing in North and South directions. So, we can find East and West directions as well by using the dial with marked directions on it.

Que. 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.

Ans. 10 The matched statements of Column I with Column II are:
