New and Useful magnetic structures are provided. One feature of the magnetic structures is that they are configured to help minimize the air gap reluctance, improving the magnetic structure's coupling coefficient. Another feature is that reducing the windings AC impedance of a magnetic structure is produced by shielding the winding under ears formed of magnetic material. Still another feature is that leakage inductance of a magnetic structure is reduced, by making ears with cuts which converge toward the magnetic rods that are used in the formation of the structure.
