MCQ
Give the SI unit of magnetic dipole moment.
- A$A ^{-2} m$
- B$Am ^{-2}$
- C$A ^2 m$
- ✓$Am ^2$
✓
Answer
Correct option: D.
$Am ^2$
The magnetic dipole moment of a magnetic dipole is defined as the product of its pole strength and magnetic length. The $SI$ unit of magnetic dipole moment is ampere metre ${ }^2\left( Am ^2\right)$. Magnetic dipole moment is a vector quantity and is directed from south to north pole of the magnet.
