NCERT Solutions for Class 6 Science Chapter 13 Topic-Wise Discussion

Fun with Magnets Class 6 begins with an introduction to magnets and their use in our daily life. It also explains how magnets were discovered and how the Greeks first discovered natural magnets. It was only after this discovery that the process for the creation of artificial magnets was discovered later. Also, there is an activity included in the chapter that students can perform at their home to understand the concepts of magnets more clearly.

The five subtopics of the chapter are discussed topic-wise below: 

  1. Magnetic and Non-Magnetic Materials

The first topic of the chapter starts with the difference between magnetic and non-magnetic objects. To simplify this process, you can perform an activity where you need to attach a magnet to the tip of a stick. After that, you can use that stick to test the various materials in your surroundings to observe if any of them gets attached to the magnet or not. You need to create a table and write down this information in it for your future reference. Another activity mentioned in the chapter clears the search for iron particles in soil or sand.

  1. Poles of Magnet

Every magnet has two poles-North Pole and the South Pole. You will be learning more about this concept in this section of Class 6 Science Chapter 13. The chapter demonstrates through an activity that the strength of a magnet is much higher on these poles.

  1. Finding Directions

One of the most important properties of a magnet is that a freely suspended bar magnet always points in the same direction, which is the N-S direction. This property has been used by travelers for centuries to find the right direction in which they should travel.

This section also discusses the story of a famous Chinese emperor who used magnets for finding directions whenever he traveled. Students can perform the different tasks included in this section at home to learn more about this concept. This section also explains how one can use a compass for finding directions. 

  1. Make Your Own Magnet

This section discusses how a magnet can be used to magnetize a piece of iron with the help of an activity. Students can follow can along and perform the given activity to make their own magnet.

  1. Attraction and Repulsion Between Magnets

Attraction and repulsion are some of the most important and useful properties of magnets. Students must always remember that like poles of a magnet repel each other whereas unlike poles attract each other.

(v) A magnet always has two poles.

Explanation: A magnet consists two poles namely the South pole (S) and the North pole (N).

Q.2 State whether the following statements are true or false:

(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.

(vi) A compass can be used to find East-West direction at any place.

(vii) Rubber is a magnetic material.

Ans-

(i) A cylindrical magnet has only one pole. (False)

Explanation: A magnet cannot exist with a single pole. A magnet always exists with two poles. Hence, a cylindrical magnet has also two poles.

(ii) Artificial magnets were discovered in Greece. (False)

(iii) Similar poles of a magnet repel each other. (True)

Explanation: Like poles of magnets repel each other, while unlike poles of magnets attract each other.

(iv) Maximum iron filings stick in the middle of a bar magnet when it is bought near them. (False)

Explanation: The magnetic strength of a bar magnet is maximum at its two poles and minimum at middle. Hence, maximum iron filings will stick at two ends of the magnet and minimum in the middle.

(v) Bar magnets always point towards the North−South direction. (True)

(vi) A compass can be used to find the East−West direction at any place. (True)

Explanation: We know that a magnetic compass always points towards the North−South direction. If the North−South direction is known, then the East−West direction can be found.

(vii) Rubber is a magnetic material. (False)

Explanation: Rubber is a non-magnetic material as it is not attracted by a magnet.

Q.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-

In a pencil sharpener, the blade is made of iron and iron is a magnetic material. Magnets have tendency to attract the objects made of iron. Hence, a pencil sharpener gets attracted towards both the poles of a magnet.

Q.5 Write any two properties of a magnet.

Ans-
Two properties of a magnet are:

i. Unlike poles of two magnets attract each other.

ii. Like poles of two magnets repel each other.

Q.6 Where are poles of a bar magnet located?

Ans-

There are two poles of a magnet namely North pole and South pole. They are located at the two ends of the magnet.

Q.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-

The poles of a bar magnet with no marking can be identified by suspending the bar magnet freely with the help of a light thread. A freely suspended bar magnet always comes to rest in the North−South direction.The north facing end of the magnet indicates its north pole while the south facing end indicates its south pole.

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

Ans-

To convert an iron strip into a magnet, place the iron strip on the table. Now, rub a permanent magnet on the strip. While doing this, the movement of your hand should always be in the same direction. After doing this 40–50 times, the iron piece would attain magnetic properties.

Q.10 How is a compass used to find directions?

Ans-

A compass has a magnetic needle which can move around a pivot. As a magnet always stays in north-south direction hence, this property of magnet is used to find the directions with the help of a compass.

Substances which can attract iron, nickel, and cobalt are called magnets. Magnets are a major part of our lives and are used in many different appliances for different purposes. Magnets have two poles namely, the North pole and the South pole.

The various uses of magnets are:

  • They are used in a computer’s hard disk and play a role in reading computer data.
  • They are used in electronics like television, speakers, radios etc. The magnet inside them helps in the transformation of the electronic signal into sound vibrations.
  • They are also used in filtering machines for separating metallic ores from crushed rock.
  • They are used in the food processing units for operating metallic pieces from grains.
  • They are even used in the medical field to cure cancers.
  • They are used in electric bells and generators as well.

It is advisable to store bar magnets always in pairs. The opposite poles of the magnet must be on the same side and a piece of wood must be kept between them as a magnet loses its magnetic property if not stored properly. 

Soft magnetic materials are those materials that can be easily magnetised and demagnetised while hard magnetic materials hold the property of magnetism for a long time and cannot be demagnetized easily. Examples of soft magnetic materials are iron and alloys of iron and nickel.
