The principle of action is being considered, design and features of the design process of the electric heater of the induction type fluid, which differs from the existing devices of similar purpose with high levels of reliability and protection against electric shock, good technical and economic indicators are considered.
It is established that the distribution of density of induced current in conducting half-space has no component perpendicular to the planar interface between media, regardless of (1) the properties of the medium, (2) configuration of a current-carrying contour, and (3) the current dependence on time. It is shown that the surface density of electric charge is determined only by the normal component of the strength of the induced electric field of the source-system of currents.
The mathematical model of an accelerator’s magnetic field, which takes into account its symmetry, the nonlinearity of an armature characteristic B(H), and eddy currents, has been investigated. The model has been developed on the basis of the finite elements method. The armature that moves under the applied Ampere’s force has been represented as a movable distribution of magnetic permeance.
