Question 2. A bar magnet is cut into two pieces A and B from the middle as shown in Figure

Will the two pieces act as individual magnets? Mark the poles of these two pieces. Suggest an activity to verify your answer
Answer.

Yes, two pieces will work as an individual magnet because a monopole (single pole) of a magnet never exists

Activity

• Place the magnet, so formed (A and B) on the table.
• Bring die north pole of both magnets towards each other, they will be repelled.
• Bring the north and south poles of both magnets towards each other, they will attract

Question 3. Given below is a figure which shows a magnetic compass. Briefly explain what will happen to the position of its needle, if you bring a bar magnet near it. Also, draw a diagram to show the effect on the needle on bringing the bar magnet near it. Also, draw the diagram to show the effect when the other end of the bar magnet is brought near it.

Answer:

When we bring a bar magnet near the compass, the needle of the magnetic compass starts deflecting. As the north pole of the magnet is brought closer to the compass, the south needle of the compass points towards it As the south pole of the magnet is brought closer to the compass, the north needle of a compass points towards it

Question 4. Three identical bars are kept on a table. Two out of three bars are magnets. In one of the magnets, the north-south poles are marked. How will you find out which of the other two bars is a magnet? Identify the poles of this magnet.
Answer:

To find out the magnet

• Take the bar magnet A in your hand.
• Take the bar magnet B in the other hand.
• Bring one side of B towards the south pole and note down
• It is attracted or repelled.
• Bring the other side of B towards the south pole and again note down the same thing.
• If there is an attraction in both cases
• It is an iron bar.
• If there is an attraction in one case and repulsion in
• other cases, then it is a bar magnet
• Do the same for the iron bar C.

To find out the poles

If in case 3. the bar is attracted, then it is the north pole of the identified bar magnet. If the bar is repelled, then it is a south pole of the identified bar magnet

Question 5. A compass is an instrument which is used to find the direction and it consists of a small metal needle which is magnetised and is free to turn in any direction.

Question 1. Boojho dipped a bar magnet in a heap of iron filings and pulled it out. He found that iron filings got stuck to the magnet as shown in figure

1. Briefly tell the regions of the magnet that have more iron filings sticking to it.
2. Mention what are these regions called.

Answer:

1. Pole regions of the magnet have more iron filings sticking to it.
2. These are called the North Pole and the South Pole, respectively.

Question 2.  Write any two properties of a magnet.
Answer:

• The two properties of a magnet are as follows
• A magnet always has two poles, i.e. north and south.
• It attracts magnetic materials like iron, nickel or cobalt.

Question 3.  Where are the poles of a bar magnet located?
Answer:

The poles of a bar magnet are located at the two ends of a bar magnet as shown below

These two poles are the north pole (N) and the south pole (S).

Question 4. A bar magnet has no markings to indicate its poles. How would you find out near which end is its north pole located?
Answer:

We can find out direction by freely suspending a bar magnet. We will find that a freely suspended bar magnet always comes to rest in the north-south direction. The end ofthe magnet that points towards the north is called a north pole. The other end that points towards the South is
called the South Pole.

Question 5. Boojho kept a magnet close to an ordinary iron bar. He observed that the iron bar attracts a pin as shown in figure

Question 6.  What inference could he draw from this observation? Explain.
Answer:

When we place any iron bar near a bar magnet, it becomes a temporary magnet and small objects like pins, iron filings can be attracted by it. But when we remove this bar from magnet, it again becomes an iron bar and does not attract the small iron objects.

Answer:

We can do a simple experiment for this

• Take tea dust on a piece of paper.
• Take a bar magnet in your hand.
• Shake the bar magnet over this dust.
• If some particles are attracted strongly towards this magnet, then definitely tea dust will have iron powder.

Question 8. Four identical iron bars were dipped In a heap of iron filings one by one. The figure shows the amount of Iron filings sticking to each of them.

1. Which of the iron bars is likely to be the strongest magnet?
2. Which of the iron bars is not a magnet? Justify your answer.

Answer:

1. The iron bar seems to be the strongest magnet because it has the maximum amount of iron filings attracted.
2. Iron bar Is not a magnet because no iron filings have been attracted by it.

Question 9. Explain whether the magnetic poles exist separately like charges or not.
Answer:

When we break a magnet from its middle, then we get two new magnets. Even if an extremely small magnet is broken into two pieces, then they will have north and south poles, i.e. a small bar magnet is obtained. So, the magnetic poles can’t exist separately like charges.
