It is well known that cutting magnetic field lines leads to the generation of an induced current and induced electromotive force in a closed circuit coil, called as electromagnetic induction. In this paper, we found that rotating a closed circuit coil in a changing electric or electrostatic field could also generate an induced current and electromotive force in the coil without any external magnets. Here we call it Electra-electric induction (EEI). This interesting discovery will be of great significance both in theory and in applications. We deduced that both Maxwell’s displacement current and the Electra-electric induced current are generated by the changing electric field. One exists in space. The other exists and flows in the conductor. Maxwell’s displacement current is collected by a coil and flows in a conductor, which is the induced current. In addition, one can expect that the extremely strong electrostatic field near the high-voltage wire, as well as the strong electromagnetic field generated by the radiation of nuclear reactor or nuclear waste dumping, can be collected by the rotated coil driven by the windmill which results in a continuous induced current flow generated. This work likely opens up new possibilities for non-electromagnetic induction and provides a new idea for the generation and transmission mode of power energy.

众所周知，切割磁力线会导致闭合电路线圈中产生感应电流和感应电动势，称为电磁感应。在本文中，我们发现在变化的电场或静电场中旋转闭路线圈也可以在没有任何外部磁铁的情况下在线圈中产生感应电流和电动势。在这里我们称之为电感应 (EEI)。这一有趣的发现无论是在理论上还是在应用上都将具有重大意义。我们推导出麦克斯韦位移电流和电感应电流都是由变化的电场产生的。一个存在于太空中。另一个存在于导体中并流动。麦克斯韦的位移电流被线圈收集并在导体中流动，这就是感应电流。此外，可以预见，高压线附近的极强静电场，以及核反应堆辐射或核废料倾倒产生的强电磁场，都可以被风车驱动的旋转线圈收集起来。导致产生连续的感应电流。这项工作可能为非电磁感应开辟了新的可能性，并为电能的产生和传输方式提供了新的思路。
