In this case, due to the high voltage and current of lightning, it may cause injury or damage to humans and objects. The main principle is that under the external environment with electrostatic field or change instant electromagnetic radiation, the effect of electric field may only cause a momentary displacement of electrons in the conductor due to the free movement of electrons on the surface of the conductor, but in general, this displacement is very small, thus the external electric field has almost no effect on the internal electrons.
