Q3. 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: There is a blade in pencil sharpener which is made up of iron. Iron is a magnetic material that is why it is attracted by the poles of magnet.

Q5. Write any two properties of a magnet.
Ans: Two properties of a magnet are as follows:
(i) Like magnetic poles repel each other and unlike magnetic poles attract each other.
(ii) A freely suspended magnet always aligns in N-S direction.


Q6. Where are poles of a bar magnet located?
Ans: The poles of bar magnet are located at its two end points.
Two PolesTwo Poles


Q7. 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 location of the poles of a magnet can be determined by suspending it freely. 
  • A freely suspended bar magnet always points in the north−south direction
  • The end that points towards the north direction is the north pole of the magnet while the end that points towards the south direction is the south pole of the magnet.


Q8. You are given an iron strip. How will you make it into a magnet?
Ans: An iron strip can be converted into a magnet by the following method:

  • Place the iron strip on a table. 
  • Place one pole of a bar magnet near one end of the iron strip. Move the bar magnet along the length of the iron strip starting from one end to the other end as shown in the following figure. 
  • Then, lift the magnet and bring the pole to the starting point and move in the same direction as before.

  • On repeating this process for at least 30-40 times, the iron strip will become a bar magnet with two poles.


Q9. How is a compass used to find directions?
Ans: 

  • A compass has a magnetic needle that can rotate freely. 
  • When a compass is kept at a place, the magnetic needle aligns in north-south direction
  • The red arrow of the compass needle is termed as the north pole and the other end as south pole.

FAQs on NCERT Solutions for Class 6 Science - Fun With Magnets

1. What is the concept of magnetism?
Ans. Magnetism is the property of certain materials to attract or repel other materials. It is caused by the alignment of the electrons within the material, creating a magnetic field.
2. How do magnets work?
Ans. Magnets work based on the interaction between their magnetic field and the magnetic field of other materials. The magnetic field of a magnet is created by the alignment of its electrons. When two magnets come close, their magnetic fields interact, resulting in attraction or repulsion.
3. What are the different types of magnets?
Ans. There are several types of magnets, including permanent magnets, temporary magnets, electromagnets, and natural magnets. Permanent magnets retain their magnetism without any external influence, while temporary magnets only exhibit magnetic properties when in the presence of a magnetic field. Electromagnets are created by passing an electric current through a coiled wire, and natural magnets are naturally occurring minerals with magnetic properties.
4. How can magnets be used in everyday life?
Ans. Magnets have various uses in everyday life. They are used in electric motors, generators, speakers, and headphones. Magnets are also used in magnetic storage devices like hard drives and credit cards. In addition, magnets are used in magnetic therapy, where they are believed to have healing properties.
5. How can magnets be used for sorting materials?
Ans. Magnets can be used to sort materials based on their magnetic properties. For example, ferromagnetic materials like iron and steel can be easily attracted to magnets, while non-magnetic materials like wood or plastic are not affected. This property can be used to separate magnetic and non-magnetic materials in various industries, such as recycling or mining.
