Question 31
4 marks · Normal
Answer and see the solution →A teacher wants to use plotting compasses to map the magnetic field around a single bar magnet.
(a)[3 marks]Describe the steps the teacher should follow to plot a single magnetic field line using plotting compasses.
(b)[1 mark]What does the direction of a plotting compass needle show about the magnetic field?
Question 32

Answer and check →Which statement about magnetic field lines around a single bar magnet is correct?
- A.They cross each other near the poles.
- B.They travel from the south pole to the north pole.
- C.They are equally spaced throughout.
- D.They are closest together near the poles.
Question 33
4 marks · Normal
Answer and see the solution →A student uses iron filings to reveal the magnetic field pattern around a bar magnet. They notice that the filings bunch together at certain locations.
(a)[2 marks]Explain why iron filings gather more closely at the poles of the magnet.
(b)[2 marks]Describe what this observation shows about the magnetic field strength near the poles compared to the middle of the magnet.
Question 34
1 mark · Easy
Answer and see the solution →State what is meant by a uniform magnetic field.
Question 35
3 marks · Easy
Answer and see the solution →(a)[2 marks]Describe an experiment you could carry out to show the magnetic field pattern around a single bar magnet.
(b)[1 mark]What would you observe in your experiment to indicate the positions of the field lines?
Question 36
1 mark · Easy
Answer and see the solution →Which arrangement of two bar magnets creates a uniform magnetic field in the region between them?
- A.Two north poles facing each other closely
- B.Two south poles facing each other closely
- C.North pole of one magnet facing the south pole of the other closely
- D.Magnets placed far apart with poles facing each other
Question 37
2 marks · Easy
Answer and see the solution →(a)[1 mark]Give one reason why it is useful to create a uniform magnetic field in an experiment.
(b)[1 mark]Describe one characteristic of the field lines between two bar magnets arranged to create a uniform field.
Question 38
2 marks · Easy
Answer and see the solution →(a)[1 mark]Name one piece of apparatus (other than iron filings) used to investigate the pattern of a magnetic field.
(b)[1 mark]State how this apparatus is used in the investigation.
Question 39
1 mark · Easy
Answer and see the solution →If two bar magnets are placed with their north poles facing each other, will the field between them be uniform or not? Explain your answer.
Question 40
1 mark · Easy
Answer and see the solution →Why do iron filings help us see the shape of a magnetic field?
