Abstract | This paper deals with the estimation of current decay rates resulting persistent current mode (PCM) performance and its affect on design of high temperature superconducting (HTS) coil models used in an HTS electromagnet. The HTS coil models were designed to generate the required magneto motive force(MMF) on HTS electromagnets operating at various levitation gaps. We simulated the current decay rate with the self-inductance and joint resistance of the superconducting coil. The current decay rates of the models for the 10 mm levitation gap were in the range of 4.5% to 18%, whereas current decay rates of the models for the 25 mm levitation gap were in the range of 2.2% to 5.3%. It was found that the HTS electromagnet for large levitation gaps had more advantages than those for narrow air gaps in regards to designing an HTS coil with better PCM performance. |

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.
