| Abstract | Summary form only given, as follows. Recently, multilayer complex plasma structures were studied in an external magnetic field In these experiments, spherical micrometer sized paramagnetic particles are levitated in the sheath region. The levitation increased with the strength of the magnetic field Moreover, some particles attracted each other and formed, elongated structures - grain chains, oriented vertically, parallel to the field lines of the external magnetic field. These features cannot be explained on the basis of pure electrostatic forces. Short-range dipole interactions between magnetized grains have to be invoked. Hence there is a need for a comprehensive treatment of various mutual dust-dust interactions, including the forces due to induced magnetic and electric moments of the grains. Which of the forces prevail is determined not only by the parameters of the dust particles, but is dependent on the discharge plasma conditions and magnitudes of the sheath electric and magnetic fields as well. Here, various mutual dust-dust interactions in complex plasmas, including the forces due to induced magnetic and electric moments of the grains are discussed. It is shown that the dipole short-range forces can be responsible for the formation of the field-aligned chains. Such chains may incorporate a few tens of individual particles, as frequently observed in experiments. |

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.
