Plasma equilibrium

Plasma equilibrium refers to a balanced state in a plasma—an extremely hot, ionized gas—inside a fusion reactor or magnetic containment device. In this state, the outward pressure from the hot plasma is perfectly balanced by the inward force of magnetic fields designed to contain it. This balance ensures the plasma remains stable and confined, preventing it from expanding or contracting uncontrollably. Achieving plasma equilibrium is essential for sustained nuclear fusion reactions, as it maintains the stable environment needed for energy production while minimizing instabilities that could disrupt the process.
