Abstract
In some examples, a variable inductor device includes a first planar loop comprising a first planar face and a material that supports electromagnetic coupling and a second planar loop comprising a second planar face and a material that supports electromagnetic coupling. The first planar loop is separable from the second planar loop to vary the inductance of the variable inductance device. In some examples, the first and second planar faces overlapping each other in a closed configuration of the device.
