Question

Following figures show the arrangement of bar magnets in different configurations. Each magnet has magnetic dipole moment $\vec{m}$. Which configuration has highest net magnetic dipole moment?(a) A(b) B(c) C(d) D

Answer 1

b(B) is correct answer because similar signs repels each other opposite attracts each other.

HOPE THIS WILL HELPS YOU.

Thank You

Answer 2

Answer:

Ans is c

Explanation:

In all 4 cases we have to find resultant dipole momnt.

The value of angle also given in the figure.

In case 2 N-S of both are opposites so cancel out each other and dipole momnet is 0.
