MCQ
When a bar magnet is broken into two pieces :
  • A
    We will have a single pole on each piece
  • ✓
    Each piece will have two unlike poles
  • C
    Each piece will have two like poles
  • D
    None of these
✓

Answer

Correct option: B.
Each piece will have two unlike poles
When we break a magnet into two, both act as magnets, that is both have a north and south pole each. In both these pieces the corresponding north and south poles remain on the sides as in the original magnet. This means that the $2$ broken sides must get oppositely polarized.
