Fun with Magnets all Questions Solution :

Multiple Choice Questions : 

Question no – (1)

Observe the pictures A and B given in Fig. 13.1 carefully

Solution : 

The correct answer is option – (d)

In A, cars 1 and 2 will come closer to each other and in B, 3 and 4 will move away from each other.

Question no – (2)

The arrangement to store two magnets is shown by figures (a), (b), (c) and (d) in Fig. 13.2. Which one of them is the correct arrangement?

Answer : 

The correct option is – (b)

Here, figure – (b) represents the correct arrangement.

Question no – (3)

Three magnets A, B and C were dipped one by one in a heap of iron filing. Fig. 13.3 shows the amount of the iron filing sticking to them.

Answer : 

The correct answer is option – (a)

The strength of these magnets will be A > B > C

Question no – (4)

North pole of a magnet can be identified by

Answer : 

The correct answer is alternative – (a)

North pole of a magnet can be identified by another magnet having its poles marked as North pole and South pole.

Question no – (5) 

A bar magnet is immersed in a heap of iron filings and pulled out. The amount of iron filling clinging to the

Answer : 

The correct answer is option – (a)

The amount of iron filling clinging to the North pole is almost equal to the south pole.

Very Short Answer Questions : 

Question no – (6) 

Answer : 

(i) When a bar magnet is broken; each of the broken part will have “Two” pole/poles.

(ii) In a bar magnet, magnetic attraction is “Stronger” near its ends.

Question no – (7) 

Answer : 

She was not able to pick up the pins using the magnet because the pins were made from stainless steel which don’t attract to magnets.

Question no – (8) 

Answer : 

We can easily check whether it is iron powder or not by bringing a magnet close to it. If it sticks to the magnet it is iron powder otherwise it is not.

Question no – (9) 

Answer : 

(i) Which regions of the magnet have more iron filings sticking to it?

= The two ends of the magnet has more fillings sticking to it.

(ii) What are these regions called?

= These regions are called poles – North pole and South pole.

Short Answer Questions :

Question no – (10) 

Answer : 

(a) Which of the iron bar is likely to be the strongest magnet?

= The magnet in figure “a” is likely to be the strongest magnet.

(b) Which of the iron bars is not a magnet? Justify your answer

= The magnet in figure “d” is not a magnet because it was not able to attract the iron fillings.

Question no – (11) 

Answer : 

In order to check the pole we have to take another magnet whose poles are already known. If the front of the car sticks with the south pole of the other magnet then the car has north pole facing outwards or vice versa.

Question no – (12) 

Answer : 

(a) (ii) Iron, (iv) Iron fillings.

(b) (iii) By another magnet.

(c) (i) Rests along a particular direction.

(d) (iii) By another magnet.

Question no – (13) 

Answer : 

The two ways to identify the magnets are as follows :

• By checking whether the bars align themselves in a particular direction when suspended freely.

• By checking whether they can attract iron fillings or not.

Question no – (14) 

Answer : 

First to identify the magnet we must bring the already know magnet to both the end of the other two bars individually. The bar’s which both ends gets attracted to the magnet is an ordinary bar while the other is an original magnet. In order to identify the poles we must bring the north pole of the known magnet to each end of the other magnet. The end which attracts is the south pole and the one that repels is north pole.

Question no – (15) 

Answer : 

The steps involved to magnetize iron strips with the help of a magnetic bar are –

• Place the iron strip

• Move one end of the magnetic bar along the length of the Iron strip without picking it

• Repeat this process 30-40 times.

Question no – (16) 

Answer : 

The magnetic needle of the compass will change it’s direction.

Question no – (17) 

Answer : 

So to prepare a compass we must first magnetize the iron needle by repeatedly rubbing the iron needle along its body by one end of the magnet. Then the magnetized needle should be in a kept in such a position that it can freely rotate like compass needle to show the north and south direction.

Question no – (18) 

Answer : 

He could infer that ordinary iron bars show magnetic properties as long as it is sticked to an another magnet.

Question no – (19) 

Answer : 

Yes, the two broken magnets will acts as an individual magnet.

Bring the poles of the magnets close to each other if the two magnets shows properties of attraction and repulsion or if it attracts iron fillings then it proves that both magnet act as an individual magnet.

Question no – (20) 

Answer : 

To store a U shaped magnet a metal plate is placed joining the two ends of the magnet.

Its quite different from the storing a bar magnet because bar magnets are always kept in pair with their unlike poles in the same direction. The magnets are kept separate by a wood piece and two iron plates placed across their ends.
