Apparent Asymmetries in Electromagnetic Interaction: A "Virtual Wire" Model for Reactionless Propulsion and Preliminary Experimental Observations

This paper, for the first time, systematically proposes and elaborates the fundamental "Principle of Electromagnetic Interaction Asymmetry." This principle states that under specific asymmetric or transient electromagnetic configurations, action and reaction forces may exhibit apparent inconsistencies in timing, direction, or internal balance relationships. Based on the third manifestation of this principle (the "disappearance" of net internal reaction force), we propose an innovative concept for reactionless propulsion. To fundamentally address its momentum conservation, this study originally establishes the "Virtual Wire" physical model. By introducing an idealized conductor segment with zero rest mass, this model conceptually closes the physical gap of the open-circuit coil into a virtual loop, thereby selfconsistently linking the net thrust acquired by the device to the directed momentum flux of the radiated electromagnetic field stemming from the structural discontinuity. For validation, two independentexperimental schemes were designed and implemented for cross-verification. The second scheme employs a center-fed toroidal drive coil and a C-shaped working coil wound with 12,000 turns of fine wire, each turn having a 70° opening. Driven at a frequency of 100 MHz with an effective current of 0.3 A, the experiment observed a repeatable average net thrust on the order of 0.1mN (estimated value). Detailed error analysis indicates that this effect significantly exceeds the uncertainty range of the measurement system. From principle proposal and model construction to experimental validation, this study provides a complete theoretical framework and preliminary experimental evidence for exploring novel propulsion technologies based on the breaking of internal electromagnetic force balance.
