Magnetic vortices are highly tunable, nonlinear systems with ideal properties for being applied in spin wave emission, data storage, and neuromorphic computing. However, their technological application is impaired by a limited understanding of non-conservative forces, that results the open challenge attaining precise control over vortex dynamics coupled systems. Here, we present an analytical model gyrotropic magnetic within nano-pillar structures, revealing how conservative forces dictate complex behavior. Validated micromagnetic simulations, our accurately predicts dynamic states, controllable through external current field adjustments. The experimental verification fabricated device aligns predictions, it showcases system's adaptability dynamical coupling. unique combined tunability inherent memory, make exemplary foundation reservoir This positions discovery at forefront utilizing innovative computing solutions, marking leap towards efficient processing technologies.
