The figure shows an arrangement of bar magnets in different configurations. Each bar magnet has a magnetic dipole moment m. The figure which has the maximum magnetic dipole moment _______ .
- A configuration (A)
- B configuration (B)
- C configuration (C)
- D configuration (D)
Answer & Solution
Correct Answer
(A) configuration (A)
Step-by-step Solution
Detailed explanation
\( M_A = m + m = 2m \) \( M_B = m - m = 0 \) \( M_C = \sqrt{m^2 + m^2} = m\sqrt{2} \) \( M_D = m - m = 0 \) \( 2m > m\sqrt{2} > 0 \) Configuration (A) has the maximum magnetic dipole moment.
