Fun with Magnets Class 6th Question Answers

Overview of Chapter

• HOW MAGNETS WERE DISCOVERED?
• MAGNETIC AND NON-MAGNETIC MATERIALS.
• POLES OF MAGNET.
• FINDING DIRECTIONS.
• MAKE YOUR OWN MAGNET.
• ATTRACTION AND REPULSION BETWEEN MAGNETS.

Magnets are substances that have the property of attracting metallic substances like iron, steel, nickel and cobalt towards themselves.

HOW MAGNETS WERE DISCOVERED? Magnets were discovered by chance by a shepherd named Magnes who lived in ancient Greece.

MAGNETIC AND NON-MAGNETIC MATERIALS: The substances which get attracted by a magnet are called magnetic materials. For Example, iron, cobalt, nickel and steel etc. The substances which are not attracted by a magnet are called non-magnetic materials. For Example, wood, plastic, rubber, paper, copper, stone diamond etc.

POLES OF MAGNET: The regions of the magnet where attractive and repulsive force is maximum are called poles of a magnet. There are two poles of the magnet i.e. the North Pole and the South Pole.

FINDING DIRECTIONS: The freely suspending magnet has the property to align itself in the North-South direction of the earth. This property is used to find directions since ancient times. A device called a compass was developed using this property of a magnet.

MAKE YOUR OWN MAGNET: There are several ways to make a magnet. The simplest way is to do it by stroking method. If we strike an iron bar with one end of the bar magnet repeatedly in the same direction, the iron bar becomes a magnet.

ATTRACTION AND REPULSION BETWEEN MAGNETS: Like poles of a magnet repel each other while unlike poles repel each other. If the north pole of a magnet is brought near the north pole of another magnet, they will repel each other while if the north pole of one magnet is brought near the south pole of another magnet, they will attract each other.

7. Magnetic poles exist in pairs. (JKBOSE)
8. Like poles of a magnet repel each other. (JKBOSE)

2. State whether the following statements are true or false

1. A cylindrical magnet has only one pole. (False)
2. Artificial magnets were discovered in Greece. (False)
3. Similar poles of a magnet repel each other. (True)
4. Maximum iron filings stick in the middle of a bar magnet when it is brought near them. (False)
5. Bar magnets always point towards the North-South direction. (True)
6. A compass can be used to find the East-West direction at any place. (False)
7. Rubber is a magnetic material. (False)

3. It was observed that a pencil sharpener gets attracted by both 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. The blade of the sharpener is made of iron which is a magnetic material. So, it is attracted by both poles of a magnet.

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.

Column I	Column II
N-N	---------
N---	Attraction
S-N	----------
---S	Repulsion

Ans.

Column I	Column II
N-N	Repulsion
N-S	Attraction
S-N	Attraction
S-S	Repulsion

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

Ans. Yes, we can convert a strip of iron into a magnet by the following method:

1. Take a rectangular strip of iron and place it on the wooden table.
2. Place one end of the bar magnet on the iron strip and drag it along the length of the iron strip from one end to another.
3. When you reach the end lift the magnet and bring the same pole of the magnet back to the starting end of the iron strip and repeat the above process.
4. Repeat the process about 30-40 times.
5. Bring an iron pin or iron fillings near the iron bar to check whether it has become a magnet. If not, continue the process of striking for some more time.
6. The pole of the magnet or the direction of striking should not change.
7. Finally, the iron bar will be converted to a magnet.

9. How is a compass used to find directions?

Ans. A compass consists of a dial which is marked with directions. It is placed where directions are to be found. Its needle always rests in the N-S direction. So, it is to be moved in such a way that marked directions coincide with the poles of the needle.

10. A magnet was brought from different directions towards a toy boat that had been floating in water in a tub. The effect observed in each case is stated in Column I. Possible reasons for the observed effects are mentioned in Column II. Match the statements given in Column I with those in Column II.

Column I	Column II
1. Boat gets attracted towards the magnet	a. Boat is fitted with a magnet with a north pole towards its head
2. Boat is not affected by the magnet	b. Boat is fitted with a magnet with a south pole towards its head
3. Boat moves towards the magnet if the north pole of the magnet is brought near its head	c. Boat has a small magnet fixed along its length
4. Boat moves away from the magnet when the north pole is brought near its head	d. Boat is made of magnetic material
5. Boat floats without changing its direction	e. Boat is made of non-magnetic material.

Ans.

Column I	Column II
1. Boat gets attracted towards the magnet	d. Boat is made of magnetic material
2. Boat is not affected by the magnet	e. Boat is made of non-magnetic material.
3. Boat moves towards the magnet if the north pole of the magnet is brought near its head	b. Boat is fitted with a magnet with a south pole towards its head
