Farley–Buneman instability is a phenomenon observed in plasmas, particularly in the context of ionospheric and magnetospheric physics. It refers to a type of instability that arises in a collisional plasma when there is a relative drift between positive ions and electrons. This relative motion creates an electric field that can lead to the growth of density fluctuations or waves.
