Following figures show the arrangement of bar magnets in different configurations. Each magnet has magnetic dipole moment . Which configuration has highest net magnetic dipole moment ?
-
- A
- B
- C
- D
Correct Option: C
| Net magnetic dipole moment = 2 Mcos | ||
| 2 |
As value of cos (θ / 2) is maximum in case (c) hence net magnetic dipole moment is maximum for option (c).
