Ion dynamics are controlled by the energy-dependent source, transport, energization and loss processes. Systematic changes in the ion dynamics are essential to understand the ring current variations in the inner magnetosphere. The Van Allen Probes mission, which orbits near the equatorial plane inside the geosynchronous orbit, has a wide energy coverage with high energy resolution and state-of-the-art ion composition instrumentation. It provides a great opportunity to investigate the plasma dynamics. In this talk, I will present some of our recent studies on the ion dynamics of different populations and species during geomagnetic quiet and active times.
