Marking points

B1 · 1 mark · Describes a correct feature (e.g., arrows showing direction, lines closer at poles, never crossing).

B2 · 1 mark · Explains importance (e.g., shows force direction, field strength, or avoids ambiguity from crossing lines).

Worked solution

Diagrams should: 1. Have arrows on the lines to show direction—this is important because it shows which way the force acts on a north pole. 2. Have the lines closer together where the field is strongest (at the poles)—this is important as it helps us see where the field is strongest.
