1.1 Methods of Investigations

The solutions to engineering tasks by applying the methods of industrial electrodynamics can be divided into several stages (Figure 1.1a):

1. Formulating mathematical equations and finding a function, which describes the electromagnetic field and its properties in the investigated region, considering the constant or variable characteristics of media (air, copper, steel, etc.) in this region

2. Determining the limiting conditions, that is, boundary conditions and initial conditions on the surface of the investigated region, imposed by the type and configuration of sources in the investigated field (configuration of conductors, coils or magnetic cores, type of current, ...
