Abstract:
A device for controlling a magnetic flux in an electromagnetic system, wherein the system includes magnetically connected magnetic cores, between which a volume is arranged. The volume includes a controllable magnetic flux region and the magnetic flux region includes a magnetic material having a relative permeability that may be varied by influencing the temperature of the material. The magnetic material includes a magnetic material, the Curie point of which lies within the temperature operating range of the device and exhibits paramagnetic properties within the temperature range. Also a method of controlling a magnetic flux.
