赫兹势是研究无源电动力学的有力工具。特别是在代数上特殊的时空背景下，Hertz势形式大大简化了麦克斯韦方程组。在天体物理学中，强电磁field.is很常见。无力电动力学是一个很好的近似。足够强的电磁场相比，惯性能量的等离子体。例如，无力模型已被广泛用于描述宇宙的磁层。stars.in在本文中，我们将赫兹势的形式主义的力自由。电动力学。Hertz势形式简化了与无源情况下一样多的无力动力学方程。作为应用，我们将赫兹势形式化到史瓦西背景。并直接得到了Brennan-Gralla-Jacobson解。
The Hertz potential is a powerful tool for the source-free electrodynamics. Especially.for the algebraically special spacetime background, the Hertz potential formalism simplifies the Maxwell equations quite much. In astrophysics, strong electric–magnetic field.is very common. Force-free electrodynamics is a good approximation for strong enough.electric–magnetic field compared to the inertial energy of the involved plasma. For example, the force-free model has been extensively used to describe the magnetosphere of stars.in the universe. In this paper, we extend the Hertz potential formalism to the force-free.electrodynamics. The Hertz potential formalism simplifies the force-free dynamical equations as much as that in the source-free case. As an application, we use the Hertz potential.formalism to the Schwarzschild background. And the Brennan–Gralla–Jacobson solutions are recovered straightforwardly.
