Method of changing a property of a polar liquid

A method of changing a property of a polar liquid, comprising:

• disposing a first transducer comprising a first electrically conductive solenoidal coil at least partially within the polar liquid, the coil formed of a plurality of loops each having an interior, the loop interiors forming an interior of the coil, wherein the polar liquid is substantially prevented from penetrating the interior of the coil, and
• applying a first alternating electrical current to the coil so as to produce an alternating magnetic field about the coil,
• wherein a portion of the alternating magnetic field penetrates the polar liquid and the first alternating electrical current has a first frequency and a first amplitude such that the alternating magnetic field has an effect on the polar liquid providing a change in a property of the polar liquid at a distance of at least 5 meters from the first transducer,
• wherein the property is gas exchange rate and the change is at least 5%, or
• the property is surface tension and the change is at least 1%, or
• the property is viscosity and the change is at least 0.5%, or
• the property is freezing point and the change is at least 0.5 degree C., or
• the property is partial vapor pressure and the change is at least 1%.
