Claim Text:
1. An electromagnetic device comprising: a magnetic flux core; an opening through the magnetic flux core; a conductor winding received in the opening and extending through the magnetic flux core, wherein 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; a core flux sensor arrangement to detect a magnetic flux level in the magnetic flux core, the core flux sensor arrangement being formed within the magnetic flux core in a path of the magnetic flux flow; 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; and wherein the core flux sensor arrangement detects the magnetic flux level in the magnetic flux core when a peak source current is flowing through the conductor winding, the core flux control system being configured to increase the electrical current flowing through the conductor winding in response to the magnetic flux level being lower than a predetermined level for the peak source current and to reduce the electrical current flowing through the conductor winding in response to the magnetic flux flow being higher than the predetermined level for the peak current.
