Working Principle

The magnetic moment (μ) of a current-carrying loop is a measure of its magnetization. It is calculated as the product of the current flowing through the loop and the area of the loop. The direction of the magnetic moment is perpendicular to the plane of the loop, following the right-hand rule.

This calculator is particularly useful in physics and engineering for analyzing the magnetic properties of current loops in electromagnets, inductors, and other electromagnetic devices.

Example

If a loop has a current of 5 Amperes and an area of 0.02 square meters, the magnetic moment would be:

Magnetic Moment (μ) = 5 A × 0.02 m² = 0.1 A·m²
