P4 Science Quiz: Magnets - Answer Key

Questions: 20
Time: 30 minutes
Total Marks: 40

Section A: Multiple Choice Questions (10 marks)

1. Which material is attracted to magnets? (2 marks)

Answer: (2) Iron nail

Explanation: Iron is a magnetic material that is strongly attracted to magnets. Plastic, wood, and glass are non-magnetic materials.

2. The ends of a magnet are called: (2 marks)

Answer: (2) poles

Explanation: Every magnet has two poles - a north pole and a south pole. The magnetic force is strongest at the poles.

3. When two north poles of magnets are brought together, they will: (2 marks)

Answer: (2) repel each other

Explanation: Like poles repel each other. Two north poles or two south poles will push away from each other.

4. Which of these is a use of electromagnets? (2 marks)

Answer: (1) Door bells

Explanation: Door bells use electromagnets that can be turned on and off with electricity to make the bell ring.

5. A compass needle always points to: (2 marks)

Answer: (2) the magnetic North

Explanation: A compass needle is a small magnet that aligns with Earth's magnetic field, always pointing toward magnetic north.

Section B: Short Answer Questions (15 marks)

6. Sort these objects into magnetic and non-magnetic materials: (4 marks)

Magnetic materials: steel paper clip, iron key, nickel coin

Non-magnetic materials: copper coin, aluminum can, plastic ruler

Explanation: Materials containing iron, steel, nickel, or cobalt are magnetic. Copper, aluminum, and plastic are non-magnetic.

7. Complete these sentences about magnets: (3 marks)

(a) Like poles repel each other.

(b) Unlike poles attract each other.

(c) The poles of a magnet are where the magnetic force is strongest.

8. Explain the difference between a permanent magnet and an electromagnet: (4 marks)

Permanent magnet: Always magnetic and cannot be turned on or off. Stays magnetic for a very long time.

Electromagnet: Only magnetic when electric current flows through it. Can be turned on and off by controlling the electricity.

9. Name two everyday objects that use magnets and explain how: (4 marks)

(a) Object 1: Refrigerator door

How it uses magnets: Magnetic strip around the door frame keeps the door closed tightly.

(b) Object 2: Speakers/headphones

How it uses magnets: Electromagnets move the speaker cone back and forth to create sound waves.

Section C: Application Questions (15 marks)

10. Siti has lost her iron ring in a box full of plastic toys, rubber balls, and wooden blocks: (4 marks)

(a) What tool can help her find the ring quickly?

Answer: A magnet

(b) Explain why this tool will work.

Answer: The magnet will attract the iron ring because iron is a magnetic material.

(c) Why won't this tool pick up the other toys?

Answer: Plastic, rubber, and wood are non-magnetic materials, so they are not attracted to magnets.

11. In a recycling center, workers need to separate iron cans from aluminum cans: (5 marks)

(a) What property of iron makes this separation possible?

Answer: Iron is magnetic (attracted to magnets) while aluminum is non-magnetic.

(b) Describe how electromagnets are better than permanent magnets for this job.

Answer: Electromagnets can be turned on to pick up iron cans, then turned off to release them in the correct bin. This is faster and more efficient than permanent magnets.

(c) Why can't they use the same method to separate plastic bottles?

Answer: Plastic is non-magnetic, so magnets cannot attract plastic bottles. Both plastic and aluminum would not be attracted to magnets.

12. Ahmad is testing different materials with a magnet: (6 marks)

(a) Which materials are definitely magnetic?

Answer: Steel spoon and iron nail

(b) Which materials are definitely non-magnetic?

Answer: Brass key and zinc coin

(c) Why might the stainless steel fork only be weakly attracted?

Answer: Stainless steel contains some iron but also other metals that reduce its magnetic properties, making it only weakly magnetic.

(d) What can Ahmad conclude about materials that contain iron?

Answer: Materials containing iron are generally magnetic, but the amount of iron and what other metals are mixed with it affects how strongly magnetic they are.

Grade Boundaries:

  • A: 36-40 marks (90-100%)
  • B: 32-35 marks (80-89%)
  • C: 28-31 marks (70-79%)
  • D: 24-27 marks (60-69%)
  • Below 24 marks: Needs improvement

Common Mistakes to Watch For:

  1. Confusing attract and repel (like poles repel, unlike poles attract)
  2. Thinking all metals are magnetic (copper, aluminum, and gold are not)
  3. Not understanding that electromagnets can be controlled with electricity
  4. Mixing up north and south poles
  5. Not knowing that magnetic force is strongest at the poles
  6. Thinking magnets only work on iron (they also work on steel, nickel, cobalt)
