In the recent years, pressure-strain interaction has received significant scrutiny in collisionless plasma. The pressure-strain interaction describes the pathway of energy exchange between the bulk fluid flow and internal energy. However, the influence of an out-of-plane (guide) magnetic field on the structure and amplitude of the pressure strain interaction has yet to be explored. In this study, using kinetic particle in cell simulations of antiparallel and guide field reconnection, we explore the changes in electron pressure-strain interaction for electrons and its decomposition into Pi-D and pressure dilatation due to the guide field close to the X-line. In addition, we perform a scaling analysis near the electron diffusion region to estimate the value of electron pressure-strain interaction as a function of upstream parameters.
