The physiologically safe magnesium is the basest metal in the electro-chemical series and, therefore, ideal as a so-called sacrificial anode. The difference in potential between magnesium and steel is about 1 Volt. As driving voltage, this causes a protective current to be discharged. In enamelled steel tanks the current flows from the magnesium anode to the defects (cathode) in the enamelling of the tank. Whereas the magnesium is gradually disintegrated through the current discharge and through intrinsic corrosion, the defects are subject to a reduced potential which can be referred to as cathodic polarisation and which prevents the steel from corroding.

The consumption of the anode has to be checked regularly, and in case of high wear the anode must be replaced.
