Question 7: How is a compass used to find directions?
Answer 7: A compass always points in the north-south direction. The compass has a red arrow present in the compass, indicating the north direction. If we get to know the north direction, then we can easily find out the other direction.
Question 8: Which arrangement is beneficial to store a U-shaped magnet? How is this different from storing a pair of bar magnets?
Answer 8: For storing a U-shaped magnet, a soft iron bar is placed on the tip of a U-magnet. To divide the bar magnets, which are placed in the same direction, a wooden block is placed between them. It is then stored in a wooden box. By following this method, the magnetic properties and strength of the magnet can be prolonged for a longer time.
Question 9: What do you mean by magnetization?
Answer 9: Magnetisation is defined as the process of creating an artificial magnet with the help of a magnet. To transform a non-magnetic material into a magnet, firstly, we must place the non-magnetic material, for example, an iron nail, on a table. Then move a strong magnet along the lengths of the iron nail without any disruptions. We must move the magnet in the same direction around 40-50 times until the iron nail becomes magnetised.
Question 10: What are the precautions to be taken care of while handling magnets?
Answer 10: Precautions to be taken while handling magnets for ensuring their magnetic strength for a longer time duration are:
- Magnets are advised to be always stored in pairs with opposite poles facing each other.
- Magnets must never be fired, hammered or thrown from a great height. This will cause the magnetic property to weaken.
- A piece of the magnet must be kept across from horseshoe magnets to avoid weakening of its magnetism.
- Magnets must be kept away from television, mobiles, CDs, laptops etc.
Question 11: State whether true or false. If false, correct the statement.
- Magnet can be used to magnetise a non-magnetic material.
A magnet can be used to magnetise other magnetic materials.
- Unlike poles of a magnet, they always repel each other.
Unlike the poles of a magnet, they always attract each other.
- Like poles of a magnet always repel each other.
- A bar magnet has equal magnetism all around its surface.
A bar magnet has maximum magnetism at the poles and least on the centre of the body.
- Magnetite is a rock with magnetic properties.
Question 12: Boojho dipped a bar magnet in a heap of iron filings and pulled it out. He found that iron filings got stuck to the magnet.
(i)Which regions of the magnet have more iron filings sticking to it?
(ii) What are these regions called?
(i) A magnet’s strength is concentrated in its ends. Hence its ends will contain more iron fillings concentration attached to them.
(ii) The ends of the magnet are called the North pole and the South pole, respectively.
Question 13: How do we determine the magnetic poles of the earth?
Answer 13: We can determine the magnetic poles of the earth in the following ways:
- Earth consists of 2 geographical poles, the north pole and the south pole.
- The North pole of the earth is Antarctica, and the south pole is named the arctic circle.
- Earth’s magnetic poles are located near each other but not exactly in the same place as geographical poles.
- A magnetic compass will always align its needle to the earth’s north pole.
Question 14: What are magnets frequently used for?
Answer 14: Uses of magnets are listed below:
- Magnets are helpful in sorting out magnetic materials from heterogeneous mixtures
- Magnets are also used in electromagnetic devices for medical purposes like MRI scan machines.
- Electromagnets are also used in electric canes and speakers etc.
- Permanent magnets are used in permanent magnets like generators, electric vehicles and in the making of a mariner’s compass.

When a magnet is suspended freely, its one pole points in the direction of the geographical north, which is called the “North Pole”. The other pole points in the geographical south direction is called “South Pole”.
Q.3 Identify the correct image if strip is suspended after magnetization as shown.
Which of the following correctly represents the direction in which the strip will rest when freely suspended in air?
The pole developed at point P will be north because the south pole of the magnet was rubbed against it. So, point P of the strip will be north seeking pole and point S will be the south seeking pole.
