μ = N · I · A
About Magnetic Moment Calculator
Estimates the dipole moment of a current loop (units A·m²), useful for torque τ = μ×B and energy −μ·B.
Frequently Asked Questions
What area should I use?
Use the geometric loop area (for a coil, the area per turn).
Units?
The result is in ampere-square-meters (A·m²), equivalent to joule per tesla.
