Utilize our free Magnetic Moment Calculator to quickly determine the magnetic dipole moment of a current loop. Simply input the number of turns, current, and radius, and get instant, accurate results. Ideal for students, engineers, and physicists needing to understand or apply the fundamental principles of electromagnetism.
Formula:
The magnetic moment (μ) of a current loop is calculated using the formula:
μ = N × I × A
Where:- μ = Magnetic Moment (measured in Ampere-square meters, A·m²)
- N = Number of turns in the loop (dimensionless)
- I = Current flowing through the loop (measured in Amperes, A)
- A = Area of the current loop (measured in square meters, m²)
So, the calculator uses the formula:
μ = N × I × π × r²
