| Abstract | Inside the ferromagnetic bodies the magnetic field is determined by applying the Finite Element Method (FEM) with a Dirichlet boundary condition for the magnetic potential. The resulting tangential component of the field intensity is used as boundary condition for the exterior field problem whose solution is obtained by the Boundary Element Method (BEM) which provides the new boundary condition for the interior problem. The nonlinearity of the highly permeable ferromagnetic material is treated by implementing the Polarization Fixed Point Method (PFPM), where the magnetic polarization is corrected in terms of the field intensity. While preserving the intrinsic advantages of the FEM and the BEM, separately, the proposed technique also allows to easily take into consideration the terminal voltage of the coils as input data and a simple field solution for multiply connected structures, such as transformers, electrical machines, and a multitude of electromagnetic devices. |

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.
