【 摘 要 】

Laboratory experiments on both metal and dielectric polarized solid particle levitation between plane electrodes at static electric field are performed. The dependence of particles charge on their mass is studied. The particle charge is found to increase with particle mass. The method to obtain extremely high electric charge on particles at atmospheric pressure is introduced. The maximum electric charge 2.8 × 107e is achieved in experiments with heavy metal particles.
