Title: The effects of inductive electric field on the spatial and temporal evolution of inner magnetospheric ring current

Abstract: The dynamic nature of the magnetic field within inner magnetosphere region plays an important role in the transport and energization process of ring current ion species, by altering the gradient-curvature drift of trapped ring current ion population and inducing an inductive electric field, as described by Faraday’s law, that accelerates particles within a short period of time. Quantifying the effect of the dynamic nature of magnetic field on ring current ion species is crucial for providing a realistic and accurate description of the dynamic and time-evolution of terrestrial ring current, especially during storm time, when the dynamic nature of magnetic field is prominent.
