Magnetic Moment
Easyphysics
Magnetic moment of single current loop (current I, area A)?
Select the correct option:
Solution
Incorrect! Answer:
I A
- Definition: The magnetic dipole moment of a current-carrying loop is a measure of its magnetic strength.
- Formula: It is defined as the product of the current (I) flowing in the loop and the area (A) of the loop.
- Equation: m=IA.
- Vector nature: The direction is perpendicular to the plane of the loop (Right-Hand Rule).
- Units: Ampere-meter squared (A·m²).
