Variable core electromagnetic device

An electromagnetic device, comprising:

• a variable magnetic flux core comprising a plurality of core sections stacked on one another, at least one core section of the plurality of core sections comprising at least one of a different selected geometry and a different chosen material from other core sections, the at least one core section being configured to provide a predetermined inductance performance in response to the at least one of the different selected geometry and the different chosen material;
• a first elongated opening through the stacked plurality of core sections of the variable magnetic flux core for receiving at least one conductor winding extending through the first elongated opening and the variable magnetic flux core;
• and
• a second elongated opening parallel to the first elongated opening through the stacked plurality of core sections of the variable magnetic flux core for receiving the at least one conductor winding extending through the second elongated opening and the variable 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 in each of the plurality of core sections of the variable magnetic flux core, the magnetic flux flow in the at least one core section being different from the other core sections in response to the at least one of the different selected geometry and the different chosen material of the at least one core section to provide the predetermined inductance performance.
