An inductor formed on an integrated circuit chip including one or more inner layers ( 12 ) between two or more outer layers ( 14 ), inductor metal winding turns ( 16 ) included in one or more inner layers ( 12 ), and a magnetic material forming the two or more outer layers ( 14 ) and the one or more inner layers ( 12 ). In one embodiment, the magnetic material is a photoresist paste having magnetic particles. In another embodiment, the magnetic material is a series of magnetic metallic strips ( 32 and 36 ) disposed on each of the first and second portions ( 30 and 34 , respectively) of the two or more outer layers ( 14 ) and on each of the one or more inner layers ( 12 ). The series of magnetic metallic strips on the first and second portions ( 30, 34 ) form a grid pattern. Other embodiments include an adjustable controlled compound deposit and control windings with adjustable electrical currents.
