A Theoretical Study of Sequential Induction and Magnetic Field Behavior Between Coils

This study presents a theoretical investigation of sequential electromagnetic coupling between multiple electrically isolated coils, referred to in this work as Sequential Induction. The study formulates the proposed configuration using conventional self-inductance and mutual-inductance theory, including a complete multi-coil matrix model and a nearest-neighbor sequential approximation. The proposed experimental configuration consists of electrically isolated coils with U-shaped ferromagnetic cores. Particular attention is given to ideal equal-stage continuation, the role of intermediate-coil loading, direct and non-nearest-neighbor coupling, and system-level real-power behavior. The central experimental question is whether the complete multi-coil system behaves as a conventional coupled electromagnetic network, exhibits stage-local power delivery that is not fully represented by the conventional model, or produces another reproducible behavior. The study is theoretical and methodological. No experimental outcome is assumed in advance. Independent experimental investigation is encouraged to determine whether the observed multi-stage behavior is quantitatively described by the conventional coupled-inductor model.
