Using state-of-the-art analytic techniques for extracting a singularity from a complex field, we can visualize the vortices in the largest time-dependent Ginsburg Landau simulation of a supercon-ductor performed to date. Our visualization reveals the internal dynamics of the vortices in the superconductor, explaining the cause of a voltage spike in the electro-magnetic response of the system. These simulations and visualizations indicate the emergence of a periodic dissipative state in a superconductor under certain external magnetic field and current conditions and explain a curious electro-magnetic response that has been observed in experiment.
