In this study, we report on the observation of ondulatory correlations between two physically isolated andelectromagnetically shielded volumes of ferrofluid. A “twinning" pre-conditioning process, involving the application of hysteresiscycles to the entire fluid volume, was performed to induce a coherent state. Subsequently, the fluid was divided into twoseparate, shielded containers, with one subjected to an electrical stimulus. We observed statistically significant correlations inthe impedance fluctuations between the stimulated and non-stimulated samples, even at a separation distance of up to 10meters. These correlations persist for approximately 100 hours under laboratory conditions and were consistently observed inboth water-based and hydrocarbon-based ferrofluids within a temperature range of 10–50◦C. The experimental design excludesclassical electromagnetic fields as the mediating force. These findings suggest the presence of a long-range, collectivephenomenon in ferrofluids, opening new avenues for investigating complex interactions in colloidal systems.
