Abstract

The conclusions drawn from previous studies, which showed that the magnetic field stimulates the formation of nanobubbles in seawater, are discussed. It was found that the air content in nanobubbles in freshwater can be neglected. Seawater contains air mainly in the form of nanobubbles, and its concentration increases with an increase in the magnetic field. The mechanism behind the influence of the magnetic field on the solubility of air in water is related to the scale reduction process during the magnetic treatment of water. The Lorentz force during the Brownian motion of charged nanobubbles decreases their electrokinetic potential and stimulates coalescence. On the one hand, this leads to the absorption of additional atmospheric air; however, on the other hand, it accelerates the rise of bubbles to the surface, reducing the total gas content of air in the water.
