Question 11
2 marks · Normal
Answer and see the solution →Explain why magnetic field lines are drawn closer together near the poles of a bar magnet.
Question 12
4 marks · Normal
Answer and see the solution →A student places two bar magnets with their north poles facing each other, 5 cm apart on a piece of paper.
Draw the magnetic field pattern that would be seen with iron filings. Include field lines and accurately label the poles.
Question 13
2 marks · Normal
Answer and see the solution →State what a magnetic field is and explain how we can make it visible in the laboratory.
Question 14
4 marks · Normal
Answer and see the solution →A student investigates the magnetic field around two bar magnets placed 5 cm apart with their opposite poles facing each other, as shown below.
(a)[2 marks]Draw the expected pattern of magnetic field lines around the two magnets.
Two bar magnets, North (left) facing South (right), labeled N and S, separated by 5 cm. (b)[2 marks]Explain why the field lines between the two magnets take the shape that they do.
Question 15
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 16
1 mark · Normal
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 17
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.
