Magnetic Moment

Question

Magnetic moment of single current loop (current I, area A)?

RankGuru · Accepted Answer

1. **Definition**: The magnetic dipole moment of a current-carrying loop is a measure of its magnetic strength.
2. **Formula**: It is defined as the product of the current ($I$) flowing in the loop and the area ($A$) of the loop.
3. **Equation**: **$m = I A$**.
4. **Vector nature**: The direction is perpendicular to the plane of the loop (Right-Hand Rule).
5. **Units**: Ampere-meter squared (A·m²).
