How do magnesium bars work to protect your SWH Tank

If two different metals are physically or electrically connected and immersed
in electrolyte then some amount of current flows between the two metals.
This current is supplied by one of the metals by emitting metal ions to the
conductive environment . This is known as galvanic corrosion which
destroys base metals rapidly.

Magnesium (Mg) alloy anodes are having greater driving potential than zinc
(Zn) or aluminium (Al). So that magnesium anodes are suitable for the
protection of pipeline, tanks, condensers, water boxes, heat exchangers,
ship hulls, boilers and marine structures from corrosion.
