On Analogies Between Hydrodynamics and Electrodynamics for Plasma Technologies I

It is shown that application of hydrodynamic equations allows to obtain analogous results for a number of experiments from a field of macroscopic electrodynamics. An analog of an electric current realized in wires represents some complex stream that creates a flow around wires. An analog of the electric field represents an acceleration of some flow, and an analog of magnetic induction-a frequency of some rotational motion in a background fluid. Momentum and continuity laws in the fluid give expressions similar to Maxwell´s equations with some differences.
