| Abstract | A single solid state magnetic sensor can measure a current flowing in a conductor in a non-contact way. In order to improve the accuracy of the measuring system and to reduce the cross-talk effects of other magnetic fields, circular sensor arrays can be fabricated, still preserving low costs. In magnetic sensor circular arrays the sensing elements are assembled on a circle around the conductor. The analogue sum of the sensor output signals is an approximation of the Ampere's circulation. A quite satisfactory cross-talk reduction from external magnetic field can be so achieved. More sophisticated algorithms that combine sensor output signals are necessary to further reduce cross-talk effects. In the paper we present an algorithm that is able to calculate the intensity of a DC current flowing in a rectangular bus-bar, in the presence of cross-talk fields. |

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.
