Marking points
D1 · 1 mark · Correctly draws two bar magnets with N and S poles facing each other.
D2 · 1 mark · Draws parallel straight field lines between the magnets.
D3 · 1 mark · All field lines have arrows pointing from N to S.
Worked solution
Draw straight, parallel field lines between N and S, with arrows pointing from N (left magnet) to S (right magnet).
