This is the discussion of a basically new electromagnetic device in which two stationary coils with no mutual inductance to each other in the ordinary definition of the term, transfer energy from one coil at one frequency to the other coil at a second frequency through the medium of a vector or field of flux which follows a lissajous locus or mode of motion. It is compared to rotary electromagnetic devices in which the more simple lissajous mode of motion or circle is used and to the transformer which has but one degree of freedom. Saturation of the core legs in sequence to become active, and alternating at a frequency different than the power source.
