Question 26
4 marks · Normal
Answer and see the solution →A student investigates the magnetic field around a bar magnet using iron filings and then plotting compasses.
(a)[2 marks]Describe how iron filings can be used to show the shape of the magnetic field around a bar magnet.
(b)[2 marks]Explain how plotting compasses can show the direction of the magnetic field around the magnet.
Question 27
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 28
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 29
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 30
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.
