ABSTRACT Water treatment by magnetic field (MF) or physical water treatment (PWT) is an attractive but still controversial issue. The main purpose of the present study was to investigate whether or not a physical water treatment reduces the surface tension of water as reported in some scientific literature. In this paper PWT phenomenon was studied by measuring surface tension of treated and untreated waters. More than 200 tests were done during a six month period in various conditions to evaluate the validity of the observed phenomenon. The test results showed that surface tension of water is too sensitive to experimental conditions to be considered as a safe and reliable indicator for studying the effects of magnetic field on water. It was found that meaningful changes in surface tension of a liquid sample after a day can be a good indicator for presence of physical or chemical changes in the sample.
