| Abstract | A theory for deriving the magnetic fields generated by monopoles of current (i.e. point sources of current) located in two volume conductor shapes is presented. The solution is derived for the magnetic field exterior to a semi-infinite conducting volume and exterior to a conducting spherical volume. In both volumes, the magnetic field of the dipole volume current is shown to be a spatial derivative of the magnetic field due to a current monopole. The magnetic field exterior to the semi-infinite volume conductor is equivalent to that of a semi-infinite line current, starting at the position of the monopole, oriented perpendicular to the surface of the conducting volume, and flowing toward infinity. The field exterior to a conducting sphere is equivalent to that generated by a finite-length line current flowing from the position of the monopole to the center of the sphere. Current monopoles can be used in lieu of dipole current sources to reduce source modeling errors and to better understand the effects of volume currents. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
