DEFINITION

Classification: 324/138

(under subclass 137) Subject matter having means to vary the time-phase relationship between two alternating magnetic fields.

(1) Note. The time-phase relationship, for example, may be adjusted so as to bring the alternating magnetic fields into time quadrature, or it may be adjusted so that they are slightly out of quadrature.
