Question

Write the expression and unit of magnetic dipole moment.

Hint:

Magnetic dipole moment quantifies the strength and orientation of a magnetic source.

Answer 1

The magnetic dipole moment \( \mu \) is given by: \[ \mu = I \cdot A \] where \( I \) is the current and \( A \) is the area of the loop. The unit of magnetic dipole moment is: \[ \text{Ampere-meter}^2 \, (\text{A} \cdot \text{m}^2) \]
