Claim:
1. A tunable inductor comprising: a magnetic core having an air gap, a tuner moveable in a radial direction within an interior space of the magnetic core in the vicinity of the air gap, and an actuator attached to said tuner which, upon actuation, moves the tuner within the interior space of said magnetic core to thereby vary the radial spacing between said tuner and said magnetic core in the vicinity of the air gap, wherein said actuator comprises a spring to bias said actuator, and wherein said tuner is movable between a first position and a second position relative to said magnetic core, wherein in said first position, the radial spacing between said tuner and said magnetic core in the vicinity of the air gap is at a minimum, and wherein in said second position, the radial spacing between said tuner and said magnetic core in the vicinity of the air gap is at a maximum.
