Show answer
(a) Arrows from N pole to S pole outside. · must show arrows from N to S outside magnet
(b) From south to north · must show south to north inside
Must show: Arrows drawn from N to S outside the magnet and from S to N inside the magnet.
Common mistakes: Arrows drawn from S to N outside the magnet.
