RENUKA 1 School of Technology and Applied Sciences, Mahatma Gandhi University, Regional Centre, Pathanamthitta, Kerala - 680 645 (INDIA) <p style="text-align: justify;">Magnetospheric substorms play an important role in determining the physical state of the geomagnetotail plasma sheet. Degree of energy transactions from the magnetosphere to the ionosphere during substorms is anlaysed against changes in the conducting properties of the sheet. The diversion of cross-tail current through the auroral ionosphere is addressed in the context of conductivity variations.</p> https://ultraphysicalsciences.org/paper/1170/ Plasma sheet electrical conductivity energy transactions magnetospheric substorm
