alleryA magnetic dipole moment of a current loop is:
AI × A (current times area)
BI/A
CI × L
DI × r
Answer & Solution
Correct answer: A. I × A (current times area)
m = IA × n̂, where A is loop area, n̂ is normal (right-hand rule).
**For multi-turn coil:** m = NIA. SI unit: A m².
Behaves like a tiny bar magnet.
