A sacrificial electrode system for cathodically protecting an iron and/or steel object against corrosion comprising of a sacrificial anodic material containing, but not limited to, zinc, magnesium, aluminum or a mixture of these materials, with a magnet, preferably of the ceramic type, coupled with a cap plate, embedded into the sacrificial anode material so that advantage can be taken of the magnetic flux for transfer of electrons from the anode material to the object being protected, the unit is affixed to the object being protected by use of an electrically conductive adhesive. The electrical connection is established via the combination of ceramic magnet and electrically conductive adhesive. The magnet is magnetized in the direction of its thickness and the conversion of Fe2O3 into Fe3O4 us furthered by the use of the electrically conductive adhesive and the magnet with cap plate.
