Simple phenomena of magnetism — practice question
Fig. 6.1 depicts a person using a magnetic window cleaner. The outer section is pulled toward the inner section through the glass pane. Each section of the window cleaner contains two magnets. Fig. 6.2 illustrates the magnetic field between the sections of the window cleaner. The diagram is labelled handle, bar magnets, inside window, and outside window.
(a)[1]
State the distinction between magnetic and non-magnetic materials.
(b)[1]
Suggest a suitable material for the magnets used in the window cleaner. Explain your answer.
(c)[1]
Label the poles on the magnets in Fig. 6.2.
(d)[1]
State how the field lines in Fig. 6.2 indicate different strengths of the magnetic field between the magnets.
