DEFINITION

Classification: 336/133

(under subclass 132) Subject matter wherein the inductor device is provided with at least two coils, one of the core portions forming a continuous flux path inductively coupling the two coils, the movable magnetic core portion being arranged between the two coils so as to provide an adjustable shunt for shunting some of the magnetic flux from the core portion forming the continuous flux path so that one of the coils may be linked by a different amount of magnetic flux than that which links the other coil.

(1) Note. An illustrative example is: [figure] [caption]MOVABLE CORE SHUNTS FLUX GENERATED BY ONE COIL FROM OTHER COIL.

(2) Note. The following illustrated types of inductor devices, below, are not included in this subclass. For the below excluded types of inductor devices, see subclasses 134+ where there is an adjustable air gap and subclass 132 for such devices without an adjustable air gap. [figure] [figure]
