The magnetic moment vector m of a bar magnet points
AAlong the field at the equatorial point
BFrom south to north pole, inside the magnet
CFrom north to south, externally
DPerpendicular to the magnet's length
Answer & Solution
Correct answer: B. From south to north pole, inside the magnet
By convention, m points from S pole to N pole within the magnet — same direction as B inside (which closes the external N → S loop).
