DEFINITION

Classification: 335/223

(under subclass 220) Subject matter including plural conductors mounted such that at least one conductor is movable relative to the other.

(1) Note. The plural conductors may be plural coils, one of which is fixed and the other is movable as in electrodynamometer, wherein the movement between the two coils is produced by the interaction of the magnetic field of the coils.

(2) Note. This subclass also includes electromagnets wherein the coil or core of the electromagnet is movable toward the armature.
