Abstract: Switchbacks, which are rapid magnetic field deflections first observed by the Parker Solar Probe, remain a puzzling phenomenon in solar wind physics. While their origins are still debated and several mechanisms are under study, recent work by Touresse et al., 2024 showed that a propagating solar jet can produce such magnetic deflections that can help in understanding switchback observations. We extend this investigation by developing new numerical experiments that intend to study the propagation of a self-induced coronal jet in a more realistic magnetic configuration including the whole 3D magnetic corona. The 3D MHD simulations rely on the Adaptive Refined MHD Solver (ARMS) code. After a relaxation phase, the jet is generated from a small bipolar active region located in an equatorial coronal hole. The system is energized by line-tied boundary motions. We present here the early results from these new simulations.
