Some Dynamics Problems for a Solid Body with Electrically Conductive Liquid Moving in Magnetic Field

Abstract

For the hole of the previous chapters the magnetic field induced by eddy currents in an electrically conductive ferromagnetic medium and the velocity field of vortex low-viscous liquid were considered independently. At the same time we noted analogy of those physical phenomena, which are rather far from each other. This analogy is reflected by similarity of the mathematical models describing them.

We have said on the other side of this page, that the definition of a spirit is a power conjoined to a body; because it cannot move of its own accord, nor can it have any kind of motion in space; and if you were to say that it moves itself, this cannot be within the elements.
