Abstract
Embodiments of the invention disclose methods of assembling and using an adjustable inductor to vary inductance. An adjustable inductor, according to embodiments of the invention, includes a wire coil configured to mount on a first side of a conductive plate. The wire coil is conductive and is a plurality of windings. A core has a first portion and a second portion. The first and second portions are configured with a plurality of grooves for threading engagement with the plurality of windings of the wire coil. The threading engagement attaches the core to the plurality of windings of the wire coil. Rotating the core results in varied inductance.
