Compass alignment with bar magnet field lines Steps:

• Compass needle aligns parallel to local magnetic field direction.
• Field lines exit north pole and curve to enter south pole.
• Near north pole (axial), field points away from pole, so needle points outward.
• On equatorial line (perpendicular bisector), field points parallel to magnet axis but opposite its N-to-S direction.

Why C is correct:

• Option C places compass on equatorial line, where field opposes magnet's orientation per right-hand rule for dipoles, matching reversed needle diagram.

Why the others are wrong:

• A: Near north pole, needle points away, not reversed.
• B: Near south pole, needle points toward pole, not parallel-opposite.
• D: Between poles, field is weak and irregular, not uniform reversal.

Final answer: C
