Marking points

B1 · 1 mark · Correctly states that field lines show the direction of the field.

B2 · 1 mark · Correctly states that field lines show the strength of the field (spacing of lines).

Worked solution

Field lines show the direction of the magnetic field and how strong it is (where lines are close together, the field is strongest).
