NCERT Solutions For Class 6 Science: Exploring Magnets: Exercise Question and Answer

Question 1.1: Fill in the blanks.

Unlike poles of two magnets ………… each other, whereas like poles each other.

Answer: Repel

Question 1.2: Fill in the blanks

The materials that are attracted towards a magnet are called ……….

Answer: Magnetic materials

Question 1.3: Fill in the blanks

The needle of a magnetic compass rests along the ……….. direction.

Answer: North - South Direction

Question 1.4: Fill in the blanks

A magnet always has ………. Poles.

Answer: Two

Question 2.1: State whether the following statements are True (T) or False (F).

A magnet can be broken into pieces to obtain a single pole. [ ]

Answer: False

Question 2.2: State whether the following statements are True (T) or False (F).

Similar poles of a magnet repel each other. [ ]

Answer: False

Question 2.3: State whether the following statements are True (T) or False (F).

Iron filings mostly stick in the middle of a bar magnet when it is brought near them.[ ]

Answer: false

Question 2.4: State whether the following statements are True (T) or False (F).

A freely suspended bar magnet always aligns with the north-south direction.[ ]

Answer: True

Question 3: Column I shows different positions in which one pole of a magnet is placed near that of the other. Column II indicates the resulting interaction between them for different situations. Fill in the blanks.

Question 4: Atharv performed an experiment in which he took a bar magnet and rolled it over a heap of steel U-clips (Fig. 4.15). According to you, which of the options given in Table 4.3 is likely to be his observation?

Table: Number of pins attracted by the magnet at its various positions


Answer: From the figure, it is clear that the ends of the magnet have more iron fillings attached to it. This is because the magnet's strength lies more at the ends of the magnet. Hence, option(i) is correct.

Question 5: Reshma bought three identical metal bars from the market. Out of these bars, two were magnets and one was just a piece of iron. How will she identify which two amongst the three could be magnets (without using any other material)?

Answer: Reshma can identify the magnets through the principle of repulsion. Magnets repel other magnets when like poles are brought close. The iron bar will only be attracted but won't show repulsion, helping her identify the magnets.

Question 6: You are given a magnet which does not have the poles marked. How can you find its poles with the help of another magnet which has its poles marked?

Answer: By bringing the marked magnet near the unmarked one, if the two ends attract, the unmarked magnet's pole is the opposite of the marked magnet's pole. If they repel, the poles are similar.

Question 7: A bar magnet has no markings to indicate its poles. How would you find out near which end its North pole is located without using another magnet?

Answer: Suspend the magnet freely, and it will align itself in the north-south direction. The end pointing towards the north is the North Pole, and the end pointing towards the south is the South Pole.

Question 8: If the earth is itself a magnet, can you guess the poles of the earth’s magnet by looking at the direction of the magnetic compass?

Answer:

Yes, we can guess the poles of Earth’s magnet by looking at the direction of the magnetic compass. The north-seeking end of the compass needle points towards the geographic North Pole of the Earth.

Question 9: While a mechanic was repairing a gadget using a screw driver, the steel screws kept falling down. Suggest a way to solve the problem of the mechanic on the basis of what you have learnt in this chapter.

Answer: The mechanic can magnetize the screwdriver by rubbing a magnet along its length several times. This will allow the screwdriver to hold the screws securely while working.

Question 10: Two ring magnets X and Y are arranged as shown in Fig. 4.16. It is observed that the magnet X does not move down further. What could be the possible reason? Suggest a way to bring the magnet X in contact with magnet Y, without pushing either of the magnets.

Answer: Magnet X must be floating because the like poles are facing each other (like poles repel each other). If we change the direction of the magnet X by rotating it the unlike poles will face each other and the magnets will come closer. Magnet X is likely repelling magnet Y because their like poles are facing each other. By rotating magnet X, so that opposite poles face each other, the magnets will attract and move closer.

Question 11: Three magnets are arranged on a table in the form of the shape shown in Fig. 4.17. What is the polarity, N or S, at the ends 1, 2, 3, 4 and 6 of the magnets? Polarity of one end (5) is given for you.

Answer:

NCERT Solutions For Class 6 Science Chapter 4: Exploring Magnets—Notes


Magnetic and Non-Magnetic Materials
Materials that are attracted to magnets are called magnetic materials.
Examples: Iron, nickel, cobalt

Materials that are not attracted to magnets are called non-magnetic materials.
Examples: Plastic, wood, glass, rubber, paper

Poles of a Magnet
Every magnet has two poles:
North Pole and South Pole

The magnetic force is strongest at the poles.
If a magnet is broken, each piece forms a new magnet with its own poles.

Finding Directions
A magnet freely suspended always points in the North-South direction.
The end pointing north is the North Pole, and the other is the South Pole.

This property is used in magnetic compasses.

Attraction and Repulsion
Like poles repel (N–N or S–S)

Unlike poles attract (N–S)

Fun with Magnets
Magnets are used in toys, fridge doors, and latches.

Frequently Asked Questions (FAQs)

1. Where can I get answers of the questions of NCERT Class 6 Science Chapter 4?

Students can access NCERT Class 6 Maths solutions chapter 4 are available for all the questions available in NCERT Class 6 Books.  

2. What are magnetic and non-magnetic materials?

Magnetic materials are those that get attracted to magnets (e.g., iron, nickel, cobalt).

Non-magnetic materials do not get attracted to magnets (e.g., plastic, wood, rubber).

3. What happens when a magnet is broken into pieces?

Each piece becomes a new magnet with its own North and South poles. A magnet can never have only one pole.

4. How can a magnet help in finding directions?

A freely suspended magnet always points in the North-South direction. This property is used in magnetic compasses to find directions.

5. What is meant by attraction and repulsion in magnets?

Like poles of magnets repel each other, while unlike poles attract. For example, North-North repels, but North-South attracts.
