Important Questions Test: Fun With Magnets - Question 3

Reeta puts two different objects in each of the following containers.
Container (i): Copper coin and iron nail
Container (ii): Steel nail and aluminium earring
Container (iii): Marble and gold can
Container (iv): Nickel coin and steel nail
She can use a magnet to separate the objects in containers

Detailed Solution for Important Questions Test: Fun With Magnets - Question 3

In containers (i) and (ii), iron nail and steel nail are magnetic while copper coin and aluminium earring are non-magnetic. In container (iii), both marble and gold coin are non-magnetic and in container (iv), both nickel coin and steel nail are magnetic. So, Reeta can use a magnet to separate the objects only in containers (i) and (ii).

Important Questions Test: Fun With Magnets - Question 7

What will happen when three bar magnets are hung in the manner as shown below?

Detailed Solution for Important Questions Test: Fun With Magnets - Question 7

We know that poles are the areas of the strongest magnetism in a magnet. That means the force of attraction or repulsion in a magnet is strongest at the poles. Like poles always repel each other while unlike poles always attract each other. Here, the south pole of the bar magnet X is facing towards the north pole of the bar magnet Y. Hence, magnet Y will be attracted by the magnet X. The two south poles of bar magnets Y and Z are facing towards each other. Hence, the magnets Y and Z will get repelled. Thus, we can conclude that magnet Y will get attracted towards magnet X and repelled by magnet Z.

Important Questions Test: Fun With Magnets - Question 8

Magnets lose their properties significantly if

Detailed Solution for Important Questions Test: Fun With Magnets - Question 8
- Magnets can lose their magnetic properties due to physical impacts.
- Dropping a magnet from a height repeatedly can misalign its internal structure, disrupting its magnetic field.
- This misalignment reduces its strength and effectiveness.
- Leaving magnets in the open or touching them with iron does not significantly impact their magnetic properties.
- Therefore, the correct answer is that dropping a magnet repeatedly can cause it to lose its magnetism.
Important Questions Test: Fun With Magnets - Question 9

A matchbox containing an unknown object is placed on a thin sheet of glass in the experimental set-up shown in the figure.

When the bar magnet moves, it is able to drag the match box along. What is most likely to be found in the matchbox?

Detailed Solution for Important Questions Test: Fun With Magnets - Question 9

The match box must contain some magnetic material i.e., steel ball bearing.

Important Questions Test: Fun With Magnets - Question 10

Which of the following is non-magnetic?

Important Questions Test: Fun With Magnets - Question 11

How many combined north and south poles are present in a magnet if it is broken into 6 pieces without loss of magnetism?

Detailed Solution for Important Questions Test: Fun With Magnets - Question 11

When a magnet is broken into pieces every piece will have 1 pair of north and south pole.
So if its broken into 6 pieces then each piece will be having one north pole and one south pole. So 6 north poles and 6 south poles, combined will be 12.

Important Questions Test: Fun With Magnets - Question 12

Two magnets are placed in a container as shown in the figure by some external force. What would happen if the force on magnet P is removed?

Detailed Solution for Important Questions Test: Fun With Magnets - Question 12

Since like poles repel each other, magnet P will repel magnet Q.

Important Questions Test: Fun With Magnets - Question 13

Materials which are attracted towards a magnet are known by which name?

Important Questions Test: Fun With Magnets - Question 14

Which of the following is incorrect?

Detailed Solution for Important Questions Test: Fun With Magnets - Question 14

Magnetic force is pulling as well as pushing force.

Important Questions Test: Fun With Magnets - Question 15

Which of the following is the best way to keep magnets?

Detailed Solution for Important Questions Test: Fun With Magnets - Question 15

Soft iron placed across the poles will preserve the magnetism for a long time.

Important Questions Test: Fun With Magnets - Question 16

Arun suspended a bar magnet on a string as shown in the diagram below. He brought 3 bar-shaped objects P, Q and R towards the bar magnet. He placed the ends (X and Y) of each object, near the north pole of the bar magnet and recorded his observations in the table below.


Which of the object(s) is/are the magnet?

Detailed Solution for Important Questions Test: Fun With Magnets - Question 16

We know that every magnet has two poles, one north pole and one south pole. The force of attraction or repulsion in a magnet is strongest at the poles. Like poles always repel each other while unlike poles always attracts each other. Thus, we can say that P and Q are the magnets here. R is not a magnet, as when its both ends are brought near to magnet, its North pole remains stationary. For the magnet P, X is the north pole and Y is the south pole whereas for magnet Q, X is south pole and Y is north pole.

Important Questions Test: Fun With Magnets - Question 17

Magnets have a shape

Important Questions Test: Fun With Magnets - Question 18

Magnetic compass is also called

Detailed Solution for Important Questions Test: Fun With Magnets - Question 18

navigational instrument. Also known as: mariners compass.

Important Questions Test: Fun With Magnets - Question 19

Two bar magnets suspended by string, are separated by a piece of metal. Which of the following statements best explain the outcome shown in the diagram?

Detailed Solution for Important Questions Test: Fun With Magnets - Question 19

The effect of magnetic field cannot pass through any metal. Magnetic effects can pass through screens of substances such as plastic, paper, glass etc.

Important Questions Test: Fun With Magnets - Question 20

Observe the given figure and identify the correct statements.


(i) Poles 1, 3 and 5 are unlike poles.
(ii) Poles 2, 4 and 6 are like poles.
(iii) Pole 1 will attract pole 3 and 5.
(iv) Pole 4 will be attracted by pole 1.

Detailed Solution for Important Questions Test: Fun With Magnets - Question 20

Poles 1, 3 and 5 are like poles, so they will not attract each other. Similarly poles 2, 4 and 6 are like poles. Only unlike poles are attracted by each other.
