I. Introduction
With the method described in the paper we can generate DC magnetic field between two independent iron cores. The value of the magnetic flux of the secondary iron core is independent of the changing speed of the flux of the primary iron core. We set up the model and it works. So it gives possibilities for the realization of novel industrial applications. The operation is based on well known physical laws but so far not applied yet in this manner. The possibility of applications is based on the principle of the magnetic flux conservation in the time in a closed loop. With this method unexpected short circuit in electrical machines are also calculated [1]. The aim of this article is not to examine higher frequencies. The measured results are relevant in the case of static and also low frequencies operating domain. The possibilities of AC application mentioned in the article are just few examples without detailed evaluation.
