In this paper the realization of a concept for an adjustable inductance with different composites of magnetic core material is described, analyzed and discussed. An electrical circuit is used to generate a magnetic field by an additional control core which is orthogonal to the magnetic field of the load core and thereby change the inductance. It is shown that the system can be influenced in different ways by the chosen material mixtures.

Advanced investigations on a previously published concept for an adjustable inductance are presented. The influence of the operating temperature will be analysed by measurement as an additional parameter for a current controlled inductor. Due to construction a defined area of the load core can be saturated to change the effective inductance. For the setup an additional core generating an orthogonal magnetic field is implemented perpendicular to a corresponding load core.
