Answer
The poles of the paper clips in Figure 8 can be labelled as follows:
The second paper clip, located just below the north pole (N) of the magnet, is labelled with the south pole (S).
The third paper clip, located below the second paper clip, is labelled with the north pole (N).
Step 2
Complete the sentence, by choosing a word from the box, to describe the type of magnetism that these paper clips have.

Answer
In Figure 9, the spacing of the magnetic field lines at point P is closer together compared to point Q, indicating that the magnetic field strength is greater at P.
Step 5

Answer
The relationship between magnetic field strength and current is that as current increases, the magnetic field strength also increases. This correlation is linear, meaning that doubling the current results in doubling the magnetic field strength.
