Usage of electrolysis. The chemical reactions take place in the electrolytes while the direct current runs through it. Herewith the electrolyte's positive ions move towards the cathode and negative ions - towards the anode. The products of chemical reduction are located on the cathode while the products of oxidation are on the anode. Usage of the corona discharge.
Gas ionizes under the influence of the corona discharge.
Dependence of the corona discharge parameters from the electrode shape and size. Usage of the ferromagnetic. Existence of the ferromagnetic self magnetic field. Screening of the magnetic field by ferromagnets. Over the Curie point the ferromagnetic transfers into the paramagnet.
