What is a magnet? Mention their classification.
A magnet is a substance that has the property of attracting objects made of iron, cobalt and nickel. On the basis of their occurrence, the magnets can be classified as:
(a) Natural magnets
(b) Artificial magnets.
What are magnetic materials? Explain with examples.
Magnetic materials are those materials which get attracted to magnets. For example, materials made of metals as iron, nickel, cobalt, etc.
What are non-magnetic materials? Explain with examples.
Answer:Non-magnetic materials are those materials that do not get attracted to magnets. For example, paper, wood, plastics, etc.
What are properties of magnets?
The properties of magnets are:
- It attracts iron pieces towards itself.
- It always aligns itself in the same direction if allowed to rotate freely.
- It is composed of oxides of iron (Fe304).
Categorise the given substances into two groups-magnetic and non-magnetic.
|Key, Glass, Wood, Nail, Book, Rubber, Fork, Sand, Iron particles, Chalk, Alpin|
|Key, Alpin, Iron particles, Nail||Glass, Wood, Chalk, Fork, Book, Rubber, Sand|
Why does bar magnet always point in north-south direction?
Bar magnet always points in north-south directions when left freely suspended because earth itself behaves likes a magnet and north pole of bar magnet is attracted towards south pole of earth’s magnet and vice-versa.
What are the poles of magnet?
A magnet has two ends. They are called poles of magnet. One is north pole (N) and the other is the south pole (S).
What is magnetic field?
The area around a magnet where its effect can be felt is known as magnetic field. It is more at the poles.
What are temporary magnets?
There are some magnets that lose their property of magnetism after a short period of time. These are called as temporary magnets.
What are the ways by which a magnet can be demagnetized?
Ways by which a magnet can be demagnetized are:
- Throwing or dropping the magnet from a height.
- Heating the magnet.
- Hammering the magnet.
- Improper storing
How should we store a magnet?
A magnet also loses its magnetism if it is not stored properly. Bar magnets must always be stored in pairs with their opposite poles on the same side. A piece of wood is kept in between to separate them. In case of horse-shoe magnet, a single magnet keeper should be kept in such a way that it should touch both the poles of the magnet.
What are permanent magnets?
The magnets that do not lose their property of magnetism even after a long period of time are called permanent magnets.
Can we isolate north pole or south pole of a magnet? Give reason.
No, we cannot isolate north pole of a magnet from its south pole or vice-versa. If we break a bar magnet into two halves, we will not get a single north or south pole but two magnets each with its north and south poles.
Draw the diagram of
(a) Bar magnet
(b) Horse-shoe magnet.

List the properties of poles of the magnet.
The poles of a magnet have some very important properties. They are:
- A freely suspended magnet always comes to rest in the north-south direction.
- Attraction is maximum at the poles of a magnet. It is because these points have maximum magnetic strength. On moving towards the centre, the magnetic power keeps on decreasing.
- Both the poles of a magnet have approximately same capacity to attract.
- Two poles of a magnet can never be separated. This means that the poles of a magnet always exist in pair in a piece of a magnet.
- Similar poles repel each other while the dissimilar poles attract each other.
How was magnet discovered?
Once upon a time in Greece, there lived a shepherd named Magnes. He used to take his herd of sheep and goats to the nearby mountains for grazing. He used to carry a stick with small piece of iron attached to it for controlling his herd. One day he was surprised to find that he had to pull hard to free his stick from a rock on the mountainside. The rock was a natural magnet that attracted the iron tip of the shepherd’s stick. This was how magnet was discovered. Such rocks were given the name magnetite, perhaps after the name of that shepherd.
How can we convert an iron strip into a temporary magnet?
The procedures for converting an iron strip into a temporary magnet are:
- Keep the iron strip on a solid surface.
- Take the bar magnet and gently rub it along the length of the iron strip.
- Repeat this activity for about 20 – 30 times.
- In order to test whether the iron strip has become a magnet or not, bring some iron nails near it and observe.
In this way, an iron strip can be converted into a temporary magnet.
What are the uses of magnets?
The uses of magnets are as follows:
- ATM, credit and debit cards have a magnetic strip that stores information and enables transactions of money.
- Magnetic recording devices such as VHS, audio cassettes, computers, floppy disks and hard disks have magnets for recording data.
- Magnets are used in junk yards to separate iron objects other waste materials.
- Magnetic compass is used to find directions. It has a small magnetic needle at its centre.
- Maglev or Magnetic levitation trains have been developed in America. These trains are without wheels and move a little above the rails.
- The trains are pulled by the magnetic force that acts on the rails.

How do the ragpickers collect iron object from roads and waste materials?
Ragpickers carry a huge magnet with them suspended with a thread. Whenever they bring the magnet near the heap of wastes having iron pieces, they stick to the magnet.
Why is compass needle is kept in a glass casing?
As compass needle is a small and thin magnetised needle, it can get affected by the air and dust setting on it. So to avoid any kind of hindrance by outer environment compass needle is kept in a glass casing.
You are given two rods. Out of these, one is an iron rod and the other one is magnet, how will you identify these rods?
Take both the rods and suspend them separately. Bring one end of a bar magnet close to both the ends of the suspended rod. If it shows attraction at both the ends then it is an iron rod. If it shows attraction at one end and repulsion at the other end then it is a bar magnet.

Sarika went to a fair nearby her house. She saw a stall with lots of people gathering there playing some game. She also went there. The game was to put a small iron ball into a hole named as ‘prize’ and if somebody does so they will win a great prize for that.
