| Abstract | Polytetrafluoroethylene (PTFE) was employed to investigate the effect of magnetic field on surface charge accumulation. The magnetic field (B) was set to make E×B drift into, away from and parallel to sample surface. An electrostatic probe was designed to measure the surface charge density. The test results showed that surface charge distribution sharply depended upon the magnetic field. When E×B drifted into PTFE, charges deposited in intensive area of the surface, the max charge density was bigger than that without magnetic field. When E×B drifted away from PTFE, charges deposited forming a barrier shape with max charge density bigger than that when E×B drifted into PTFE. When E×B was parallel to PTFE, charge accumulation was flat with max charge density smaller than that without magnetic field. Furthermore, the max charge density increased by varying the magnetic flux density from 70 mT to 140 mT. |

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.
