Abstract
An electromagnetic device may include a magnetic flux core and an opening through the magnetic flux core. A conductor winding may be received in the opening and extend through the magnetic flux core. An electrical current flowing through the conductor winding generates a magnetic field about the conductor winding and a magnetic flux flow about the opening in the magnetic flux core. The electromagnetic device may also include a core flux sensor arrangement to detect a magnetic flux level in the magnetic flux core. The electromagnetic device may additionally include a core flux control system configured to adjust the electrical current flowing through the conductor winding to control the magnetic flux level in the magnetic flux core.
