ABSTRACT
This chapter examines the equation of motion of the ideal medium (fluid) in which there is no viscous friction and no heat conductivity processes. It also examines the motion of the fluid in a rectangular parallelepiped with the faces of the latter parallel to the coordinate axis. The chapter discusses the oscillatory systems with concentrated parameters in which the active elements are nano-and microdiarticles media. The magnetic micro-or nanoparticles, distributed on both sides from the interface, is situated in magnetic fields of different strength. The cross-section of a pipe wand a radius is overlapped by a plane-parallel layer of the magnetic fluid. A suitable example of the formation of conical peaks on the surface of the magnetic fluid is a photograph of the surface of the magnetic fluid membrane formed in a heterogeneous field of a ring-shape magnet.
