Which conclusion follows most directly from the note that a freely suspended bar magnet points north-south?
AThe bar magnet has no poles
BThe earth exerts an orienting magnetic effect on the magnet
CThe magnet must be electrically charged
DThe magnet attracts every object placed near it
Answer & Solution
Correct answer: B. The earth exerts an orienting magnetic effect on the magnet
If a freely suspended magnet consistently aligns north-south, it implies that the earth provides a directional magnetic influence that orients the magnet. The statement does not imply electric charge or universal attraction.
