WebA Plasma instability is a region where turbulence occurs due to changes in the characteristics of a plasma (eg. temperature, density, electric fields, magneti fields). As the name suggests, instabilities are unstable, though they may appear to evolve through different forms (morphology). Similar types of instability are common in fluids (liquids …
