When a neutral conductor experiences induced charge and is then grounded, electrons from the ground will flow into the positively charged side, resulting in a net negative charge for the conductor. If a charged object induces a separation of charges in the conductor and only one side is grounded, the conductor will retain an unbalanced charge after the charged object is removed. For example, grounding the far side of a conductor while a negatively charged sphere is nearby will leave the conductor positively charged. Conversely, grounding the far side while a positively charged object is present will result in a net negative charge. This phenomenon illustrates the principles of electrostatic induction, as exemplified by Lord Kelvin's thunderstorm.
