# Illustration A circular current generates magnetic dipole moment

An electric current $$\class{red}{I}$$ running in a circle encloses an area $$A$$ and generates a magnetic dipole moment $$\mu = \class{red}{I} \, A$$. The magnetic dipole moment $$\boldsymbol{\mu}$$ is perpendicular to the enclosed surface and points in the direction of the surface normal vector.
