Abstract: An apparatus for generating an electromagnetic field in water. The apparatus comprises a set of spaced electrically conductive rings, which are respectively positively charged (rings 2, 6) and negatively charged (rings 3, 5). The rings are on a common axis between a negative plate (1) and a positive plate (7) and have precise spacings and dimensions. A central neutral ring (4) separates the pairs of rings. The electromagnetic field generated is such as to produce increases in the organic electrolytic functionality of living cellular material which is contacted with the water.
