Important Questions Test: Exploring Magnets - Question 1

What are materials called that are attracted to magnets?

Detailed Solution for Important Questions Test: Exploring Magnets - Question 1
  • Materials that are attracted to magnets are known as magnetic materials.
  • Iron is a primary example of such a material.
  • Nickel and cobalt are also magnetic, while wood, plastic, and rubber are not attracted to magnets.
Important Questions Test: Exploring Magnets - Question 2

Which of the following is a non-magnetic material?

Detailed Solution for Important Questions Test: Exploring Magnets - Question 2
- Nickel, cobalt, and iron are all magnetic materials that can be attracted to magnets.
- These metals have ferromagnetic properties, which means they can be magnetized and will respond to magnetic fields.
- Wood, on the other hand, is a non-magnetic material.
- It does not contain any magnetic properties and therefore is not attracted to magnets.
- Common non-magnetic materials include wood, plastic, and rubber.
Important Questions Test: Exploring Magnets - Question 3

Which part of a magnet has the strongest magnetic force?

Detailed Solution for Important Questions Test: Exploring Magnets - Question 3
The magnetic force is strongest at the poles of a magnet, where iron filings tend to accumulate.
Important Questions Test: Exploring Magnets - Question 4

What happens if you cut a bar magnet in half?

Detailed Solution for Important Questions Test: Exploring Magnets - Question 4

option c

Explanation: When you cut a magnet, you are essentially creating two smaller magnets, each with its own distinct North and South pole. This is because the magnetic field within the magnet is continuous, and there is no way to isolate just one pole. 

Why other options are incorrect:

  • a) Each piece will have only one pole:

    This is impossible because a magnet must always have both a North and a South pole. Magnetic monopoles (poles with only one type of magnetism) do not exist in nature. 

  • b) The magnet will lose its magnetism:

    Cutting a magnet does not destroy its magnetism. It simply creates two smaller magnets with the same polarity. 

  • c) The poles will disappear:

    The poles do not disappear, they simply redistribute themselves to form new North and South poles on the newly cut surfaces. 

Important Questions Test: Exploring Magnets - Question 5
How does a freely suspended magnet behave?
Detailed Solution for Important Questions Test: Exploring Magnets - Question 5
- A freely suspended magnet can rotate and is not fixed in place.
- When it is allowed to move, it aligns itself along the Earth's magnetic field lines.
- The Earth acts like a giant magnet; thus, one end of the magnet (the north pole) points toward the Earth's magnetic north pole, while the other end (the south pole) points toward the magnetic south.
- This alignment creates a north-south orientation, making option 2 the correct answer.
Important Questions Test: Exploring Magnets - Question 6
Which device is used to determine directions using a magnet?
Detailed Solution for Important Questions Test: Exploring Magnets - Question 6
A magnetic compass contains a needle that aligns with the Earth's magnetic field to indicate direction.
Important Questions Test: Exploring Magnets - Question 7

Which of the following best describes the attraction between two magnets?

Detailed Solution for Important Questions Test: Exploring Magnets - Question 7

Magnets have two poles: North (N) and South (S). The behaviour of magnetic poles is as follows:

  • Like poles (N–N or S–S): Repel each other.
  • Opposite poles (N–S or S–N): Attract each other.

This is a fundamental property of magnetism.

Why are other options incorrect:

a) Like poles attract → Incorrect, they repel.

c) Both like and opposite poles attract → Incorrect, like poles repel.

d) Magnets never attract each other → Incorrect, they can attract if opposite poles face each other.

Important Questions Test: Exploring Magnets - Question 8
Why does a compass needle always point in the north-south direction?
Detailed Solution for Important Questions Test: Exploring Magnets - Question 8
  • The Earth has a magnetic field generated by the movement of molten iron in its outer core.
  • This magnetic field creates magnetic poles, with the North Pole being a magnetic south pole.
  • A compass needle is a small magnet that aligns itself with the Earth's magnetic field.
  • As a result, one end of the needle points towards the magnetic North, while the other points towards the magnetic South.
Important Questions Test: Exploring Magnets - Question 9
How can you make a simple compass at home?
Detailed Solution for Important Questions Test: Exploring Magnets - Question 9
A magnetized needle placed on a floating cork in water aligns itself in the north-south direction, acting as a simple compass.
Important Questions Test: Exploring Magnets - Question 10
Which ancient Indian navigation tool was used to find directions?
Detailed Solution for Important Questions Test: Exploring Magnets - Question 10
The Matsya-Yantra, a fish-shaped magnetized iron piece placed in oil, was used for navigation in ancient India.
Important Questions Test: Exploring Magnets - Question 11

What happens when you place a steel paper clip near a magnet?

Detailed Solution for Important Questions Test: Exploring Magnets - Question 11

Steel is a magnetic material because it contains iron. When you bring a steel paper clip near a magnet, the magnetic field of the magnet induces magnetism in the paper clip. This causes the paper clip to be attracted toward the magnet.

Why not the other options?

a) Repelled → Only like poles of magnets repel; a paper clip is not a magnet initially.
c) Loses its shape → Magnetic field does not deform objects.
d) Magnet becomes non-magnetic → The magnet retains its magnetism; it is unaffected by simply attracting a paper clip.

Important Questions Test: Exploring Magnets - Question 12
Which of the following is NOT a proper way to store magnets?
Detailed Solution for Important Questions Test: Exploring Magnets - Question 12

Magnets should be kept away from electronic devices, as they can interfere with their functioning.

Important Questions Test: Exploring Magnets - Question 13
What is the function of a magnetic compass?
Detailed Solution for Important Questions Test: Exploring Magnets - Question 13
- A magnetic compass is a navigation tool that helps determine direction.
- It uses a magnetized needle that aligns itself with the Earth's magnetic field.
- The needle points towards magnetic North, allowing users to find their bearings.
- By knowing which way is north, individuals can orient themselves and navigate to their desired destination.
- This makes the compass essential for activities like hiking, sailing, or any situation where direction is needed.
Important Questions Test: Exploring Magnets - Question 14
What happens when you bring two like poles of a magnet close together?
Detailed Solution for Important Questions Test: Exploring Magnets - Question 14
Like poles repel each other due to the nature of magnetic forces.
Important Questions Test: Exploring Magnets - Question 15

Which of the following is an example of using magnets in daily life?

Detailed Solution for Important Questions Test: Exploring Magnets - Question 15

Answer: d) All of the above

a) Magnetic compass — The needle is a tiny bar magnet. It aligns with Earth’s magnetic field, so one end points toward magnetic north.

b) Magnetic door locks — These use an electromagnet and a metal plate. When current flows, the magnet holds the door firmly shut; when power cuts, it releases.

c) Refrigerator magnetsPermanent magnets that stick to the steel door, used to pin notes or decorations.

d) All of the above — All three are everyday applications of magnets, so this is correct.
