ABSTRACT:
A biased gap inductor includes a first ferromagnetic plate, a second ferromagnetic plate, a conductor sandwiched between the first ferromagnetic plate and the second ferromagnetic plate, and an adhesive between the first ferromagnetic plate and the second ferromagnetic plate, the adhesive comprising magnet powder to thereby form at least one magnetic gap. A method of forming an inductor includes providing a first ferromagnetic plate and a second ferromagnetic plate and a conductor, placing the conductor between the first ferromagnetic plate and the second ferromagnetic plate, adhering the first ferromagnetic plate to the second ferromagnetic plate with a composition comprising an adhesive and a magnet powder to form magnetic gaps, and magnetizing the inductor.
