Consider below a single mnetal insulated sphere, (a) initially uncharged. When a negatively charged rod is nearby, (b), charges in the metal are separated. Electrons are repelled to the far side. When the sphere is touched with your finger. (c). electrons flow out of the sphere to Earth through your hand. The sphere is "grounded." Note the positive charge remaining (d) while the rod is still present and your finger removed, and (e) when the rod is removed. This is an example of charge induction by grounding. In this procedure the negative rod "gives" a positive charge to the sphere. The diagrams bolow show a similar procodure with a positive rod. Draw the correct charges for a through e.

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
