A method for calculating the magnetic fields of volume currents by using point current sources (monopoles) is derived. A model is developed for a point source that is consistent with Maxwell's equations. An arbitrary arrangement of point sources in a conducting volume is shown to generate no magnetic field outside the conductor if the volume surface coincides with an equipotential surface of the sources. This allows such sources to be added to any problem without affecting the magnetic field, and simplifies the calculation of the magnetic field generated by an arbitrary point source in both spherical and semi-infinite volume conductors. The magnetic field generated by current monopoles located within these volume conductors is then derived. The formulation greatly simplifies the analysis of the magnetic field generated by higher-order current sources, notably dipoles, in these volumes.
