The magnetic field due to a magnetic dipole  can be calculated as

where the magnetic dipole can be implemented by a current loop of area

a carrying current i with . This field is dual to the electric field

generated by an electric dipole moment of , namely,

            Electric Field of an Electric Dipole [V/m]                                     Electric Potential of an Electric Dipole [V]

            Magnetic Field of a Magnetic Dipole [A/m]                                Magnetic Potential of a Magnetic Dipole [A]
