# Field of a static magnetic dipole

## Description

A magnetic dipole is a closed circulation of electric current. A simple example of this is a single loop of wire with some constant current through it.Dipoles can be characterized by their dipole moment.

The far-field strength of a dipole magnetic field is related to the distance from the center, the magnetic latitude and the dipole moment (VADM=virtual axial dipole moment).
