| Abstract | The domain-refinement technique which was developed to decrease anomalous eddy-current loss showed remarkable effect. The LASER-scribing method enabled the development of industrial products. Moreover, when this domain-refinement was applied to thinner gaged core material, the effect appeared in a marked degree. In this paper, the improvement of magnetic Properties of 0.23mm thick domain-refined core material is emphasized, because it has been used widely. It was clarifyed that the effect of domain-refinement depended on the thickness of core materials and the induction at 1000A/m strongly. The core losses, 0.80W/kg at 1.7T, 50Hz and 0.59W/kg at 1.5T, 50Hz were successfully obtained for an industrial product, 0.23mm HI-B. When the LASER-scribing was applied to very high permeability HI-B, the hysteresis loss was little changed, but the eddy-current loss decreased sharply. Further, by the numerical analysis with actually measured data, the Building Factor was also improved by the patterns of the LASER-scribing. |

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.
