| Abstract: | Force-free magnetic fields have been widely applied to simulating strong magnetic fields in solar active regions. Based on the Bernstein energy principle, this paper derives a general form of energy principle for force-free fields and presents several sufficient conditions for stability, which may be used to conveniently and effectively form a judgement on the stability of force-free fields. |
