Embodiments of the present invention are directed to methods and systems for treating irrigation water by introducing a propagating electromagnetic field into the irrigation water as it flows through an irrigation system. The treatments described herein may have a variety of beneficial effects on the water, including a significant increase in the percentage of the water that is maintained in the root zone of a given crop as plant-available water and the essential mineral, e.g. calcium and/or magnesium, uptake of that crop.

Electromagnetic processing of fluid materials is disclosed. Separation of one or more ionic components of a fluid, and combination of one or more ionic components in a fluid, are discussed.

A method is described for controlling an oil spill by seeding micron-sized magnetizable particles in the oil. Once seeded, particles can form a unique and preferential bond with the oil resulting in creation of a colloidal mixture. This bond forms as a result of a combination of forces including the intermolecular Van der Waal forces. Once this bond is formed, the oil is rendered magnetic and can be controlled and moved in response to a magnetic field. This can include removing oil from water, reducing the diffusion rate of oil on water, magnetically lifting oil from water or nonporous surfaces, as well as separating the magnetic material from the oil.

For changing a property of a polar liquid, a transducer including a solenoidal coil is disposed at least partially within the liquid, which is prevented from penetrating the interior of the coil. An alternating electrical current applied to the coil produces a magnetic field about the coil. The current has a frequency and an amplitude such that the magnetic field has an effect on the liquid changing a property of the liquid at a distance of at least 5 meters from the transducer, wherein the property is gas exchange rate, surface tension, viscosity, freezing point, or partial vapor pressure. A system may include two transducers, wherein the electrical currents are offset in phase or frequency for controlling the effect.

A system for treating a polar liquid includes a signal generator for providing an alternating electrical current, and a transducer electrically coupled to the signal generator. The transducer includes a solenoidal coil and two ferromagnetic end pieces at the ends of the coil and transverse thereto. In operation, the transducer is at least partially immersed in a polar liquid and, when energized with the current provides a magnetic field into the liquid, the field may change a property of the liquid, e.g. an interfacial mass transfer rate. This can be used in many different industrial applications.
