exist in nature, therefore they don't contribute to the magnetic field. Electric monopoles (isolated electric charges) exist but do not contribute for the common case of materials with no net electrical charge.

Any configuration of charges or currents has a 'dipole moment' whose field is the best approximation, at large distances, to that of that configuration. The field of a dipole falls off in proportion to , as compared to for the next (quadrupole) term and higher powers of for higher terms.
