Abstract | The magnetization property is one of the key issues when considering the accelerator-magnet applications of Bi-2212 wires. In this work, first, the critical current densities of several types of Bi-2212 round wires were measured by the transport current method at various temperatures. Then, the magnetization of the wires was measured at various temperatures and applied field amplitudes using the SQUID magnetometer. Hysteresis loops were plotted, and the time decay of the magnetization was studied. It was observed that magnetization had various values, but the hysteresis curves and time decays of all samples had the same tendency. The equivalent filament diameter can be determined from the measured magnetization and the measured critical current density. The equivalent filament diameters are several times larger as compared with the actual filament size. |

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.
