Understanding the factors influencing the magnetic fields induced by ionic currents is essential for various applications ranging from biophysics to materials science. In this study, we systematically investigated the magnitude of the ionic-current-induced magnetic field under diverse conditions, including different current intensities, distances, coil numbers, and conduit sizes and shapes. Our experimental results reveal that the magnetic flux density is directly proportional to the current intensity and decreases with larger distances. Furthermore, it increases with the number of effective coils and decreases with larger conduit sizes, demonstrating the significant impact of conduit shape on the generated magnetic field. To complement our experimental findings, we conduct comprehensive data simulations, revealing a close agreement between simulation results and experimental data. This convergence underscores the robustness of our experimental observations and provides further insights into optimizing ionic current-induced magnetic fields. Overall, our study offers valuable insights into the design and optimization of systems utilizing ionic-current-induced magnetic fields for a wide array of applications.
