| Abstract | Experimental results showing I/sub c/ versus length for long Ag/Bi(Pb)-2223 multifilament tapes are presented. The results are obtained using a contact-free method (Hall probe) measuring the shielding and remanent magnetic fields created by tapes when exposed to an external magnetic field. The main goal of this paper is to study the potentials of the applied method and the study includes reproducibility, resolution, non-destructiveness and usefulness in the production of tapes. The results show that the reproducibility is so high that the method can be used to identify individual tapes by their signal pattern and the spatial resolution is demonstrated to be as good as a few mm. The non-destructiveness is generally good. The first cycle/re-coiling of a tape may decrease the critical current by less than 2%, and each following cycle is observed to have an effect of less than 0.5%. This contact-free method offers the tape manufacturer a detailed picture of the superconductive properties of the final product and is therefore a good tool for product development and quality control. |

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.
