Abstract
Embodiments of the present invention provide a tunable inductor having a magnetic core which has an air gap. In order to vary the inductance of the inductor, the inductor includes a tuner that is moveable relative to the magnetic core in the vicinity of the air gap. An actuator is attached to the tuner which, upon actuation, moves the tuner relative to the magnetic core to thereby vary the spacing between the tuner and the core in the vicinity of the air gap. The variation of the spacing between the tuner and the magnetic core varies the effective air gap of the overall inductor in the desired fashion.
