The diagram of ₂₀  variation with respect to l   and k  is shown in Fig. 24.

Alike, comparing in Fig. 25 the calculation results with those experimental shown in Fig. 20, we will make sure of their consistence.

Thus, the experiment conducted to study the emf induced in a single probe by two windings with inequal alternating voltages, as well as a full fit of calculation based on summation of emfs excited by each of primary loops separately, with the experimental results, shows the process of dynamic induction to be the result of currents of primary loop affecting the elements of secondary loop in direction parallel to these currents and opposing them. This finally corroborates the fact that dynamic magnetic field basically differs in its properties and structure from stationary magnetic field. In particular, if stationary magnetic field was able to affect only moving charges, dynamic magnetic field is able to excite directed motion of charges parallelly or oppositely to the induced current.

If there exists some spatial distribution of inducing currents, the resulting emf will be determined by the geometric sum of emfs induced by each current separately. This to a definite extent links this process with interference of light beams. This rises many important questions of the nature and structure of dynamic magnetic fields which require to be thoroughly and many-sided studied. Though this exceeds the frames of present paper in which we only experimentally corroborated the theoretical proof of paper [1] that the lines of force of dynamic magnetic field are open.
