A method of protecting a ferrous metal structure, which is embedded in water or moist soil, from corrosion due to galvanic action; usually by attaching it to a metal rod which is more electronegative than the structure, or by counteracting the current which is the source of corrosion by another one (in the opposite direction) which just balances it.
