Question 31
1 mark · Easy
Answer and see the solution →What do we call the region around a magnet where magnetic forces can be detected?
Question 32
1 mark · Easy
Answer and check →Which statement best describes the direction of magnetic field lines around a bar magnet?
- A.They travel from north to south outside the magnet.
- B.They travel from south to north outside the magnet.
- C.They form random loops around the magnet.
- D.They always point towards both poles.
Question 33
1 mark · Easy
Answer and see the solution →State what is meant by the term ‘magnetic field line’.
Question 34
2 marks · Easy
Answer and see the solution →A student uses iron filings to show the magnetic field around a bar magnet. The filings form a dense pattern near the ends of the magnet and are more spread out in the centre.
Explain what this tells you about the magnetic field near the ends, compared to the centre of the magnet.
Question 35
3 marks · Easy
Answer and see the solution →Look at the diagram below, showing a bar magnet lying flat on a table.
Bar magnet with poles labelled. (a)[2 marks]Add arrows to the diagram to show the direction of magnetic field lines outside the magnet.
Draw at least two field lines from the north to the south pole.
(b)[1 mark]State the direction of the magnetic field inside the bar magnet.
Question 36
2 marks · Easy
Answer and see the solution →Explain why magnetic field lines never cross each other.
Question 37
3 marks · Easy
Answer and see the solution →Two bar magnets are placed near each other on a table. Their north poles are facing each other about 5 cm apart.
(a)[1 mark]Describe what will happen to the magnets.
(b)[2 marks]Draw a labelled diagram to show the magnetic field lines between the two magnets.
Question 38
2 marks · Easy
Answer and see the solution →Describe two features that a diagram of magnetic field lines should include, and explain why each feature is important.
Question 39
4 marks · Normal
Answer and see the solution →A student investigates the magnetic field around a bar magnet using iron filings.
(a)[2 marks]Describe how the student should arrange the apparatus to show the pattern of the magnetic field around the bar magnet using iron filings.
(b)[2 marks]State what can be learned about the magnetic field from the pattern of the iron filings.
Question 40
4 marks · Normal
Answer and see the solution →A student investigates the magnetic field around a bar magnet using plotting compasses.
(a)[2 marks]Describe how the student should use plotting compasses to show the direction of the magnetic field around the bar magnet.
(b)[2 marks]State what is meant by a magnetic field line and explain what information about the field is provided by the direction and spacing of the lines.
