MCQ
Two identical bar magnets are held perpendicular to each other with a certain separation, as shown below. The area around the magnets is divided into four zones. Given that there is a neutral point it is located in
  • ✓
    zone $I$
  • B
    zone $II$
  • C
    zone $III$
  • D
    zone $IV$
✓

Answer

Correct option: A.
zone $I$
a
(a)

Neutral point appears in region in which fields of magnets are in opposite directions.

From above figure, we can conclude that magnetic fields cancel each other in region $I$ only.
