DEFINITION

Classification: 340/870.33

Flux valve type (e.g., with movable saturating magnet):

(under subclass 870.32) Subject matter in which the mutual inductance is controlled by variably saturating a magnetic field.

(1) Note. The saturation may be produced, for example, by a movable saturating magnet or by the earth's magnetic field.
