Magnetic structures and inductive coupling control

An apparatus comprising:

• a core. the core being a single element of magnetic permeable material;
• an arrangement of multiple electrically conductive paths extending through the single element of magnetic permeable material, the multiple electrically conductive paths including a first electrically conductive path and a second electrically conductive path:
• the single element of magnetic permeable material fabricated to include at least one cutaway portion operative to reduce inductive coupling between the first electrically conductive path and the second electrically conductive path;
• a first cell in which the first electrically conductive path resides, the first cell disposed in a first portion of the single element of magnetic permeable material:
• a second cell in which the second electrically conductive path resides, the second cell disposed in a second portion of the single element of magnetic permeable material:
• wherein a third portion of the single element of magnetic permeable material is disposed between the first cell and the second cell;
• wherein the single element of magnetic permeable material includes a top surface, a bottom surface, a first side surface, and a second side surface;
• and
• wherein the at least one cutaway portion includes a first cutaway portion disposed in the top surface between the first side surface and the second side surface.
