FIELD: electricity.
SUBSTANCE: variable inductance coil has inductance value that can be switched between two or more values. It includes multiple-loop primary inductance coil which is electromagnetically connected to pair of secondary inductance coils. The latter are connected to each other to form closed loop within the limits of which they have variable topology switched between series and parallel connections to change inductance value, which is provided with multiple-loop primary inductance coil.
EFFECT: enlarging control range.
